VHT Engine Paint Review – The Best Engine Paint in 2021

While most car engines come in nice and alluring gloss when new, they gradually (or rapidly) lose that luster as you use them.

Interestingly, not only does engine painting create a better aesthetic look for ‘your baby’ (your car in this caseJ), but it also prevents corrosion and rust.

In addition to that, some engine paints (especially the darker colors) bring about better heat dissipation, allowing the engine to cool off much more rapidly [1]. Awesome? Right!

Regardless of your motivation to beautify your car engine, you need to ensure you use the best engine paint. However, this is not the easiest of tasks, as there are loads of options to choose from.

You need not worry anyway. This VHT engine paint review is here to make your decision-making process more straightforward and spot on.

Reviews of the Best VHT Engine Paint

1. VHT SP145 Engine Enamel Gloss Clear Can - 11 oz.

VHT SP145 Engine Enamel Gloss Clear Can - 11 oz.

SP145 is unarguably the best VHT paint around, especially for high heat application.

With its brilliant color and bright shine in the sunlight, you can make your engine look great and eye-catching again.

But is it easy to apply? YES! 

The application is seamless, and the overall result looks incredible. I've used other paints in the past that required complicated techniques to come out great. But this VHT paint was pretty easy to use.

While some paints have poor coverage, VHT SP145 dries in about no time. In fact, it dries to touch within thirty minutes.

Also, this engine paint sprays nicely. Although the manufacturer suggests two (light) coats followed by a medium coat - with ten minutes intervals between coats, I recommend that you apply all coats within one hour. You might have to wait for seven days for it to cure properly if any additional coat is added after sixty minutes.

Any downside? Yeah, there are a few of them.

The painting takes several light coats as opposed to the manufacturer’s instruction that specifies one thick coat top-off. Also, the paint is not returnable.

However, considering its great features and smooth application, I call this product the ‘perfect paint’ for a ‘perfect job.’

2. VHT SP403 Engine Metallic Titanium Silver Blue Paint Can - 11 oz.

VHT SP403 Engine Metallic Titanium Silver Blue Paint Can - 11 oz.

VHT SP403 is a high-performance painting system for quality and ultimate protection. And not only does it look great, but it also lasts really well.

This product is a great blend of ceramic resins and urethane, which gives a lasting and sparkling finish. It is formulated to withstand rust, corrosion, chemicals, salt spray, degreasers, and temperatures of about 650 degrees Fahrenheit.

Also, this engine paint’s color is fantastic and with some metallic quality. Although its price is slightly on the high side (compared to other products in this review), it covers really well, is durable, and pretty easy to use.

Any downside? Yes, there are.

There’s often a color mismatch, and the nozzles get clogged. Nevertheless, the nozzle spray pattern is impressive and lays on spray fine.

However, I advise you to read on how to cure VHT engine paint consistently to maximize its durability. If you rely on your engine parts to heat it to cure, you might end up with a mess.

Overall, this product is good, durable, and resistant to harsh conditions so long as you prep the surface properly after curing.

3. VERY HIGH TEMPERATURE VHT Engine Enamel SP139 GM Satin Black 11 oz Spray

VERY HIGH TEMPERATURE VHT Engine Enamel SP139 GM Satin Black 11 oz Spray

VHT SP139 engine paint works well and has an excellent quality as well as a high-end spray nozzle can.

This engine enamel can withstand heat up to 288 degrees Celsius. It is a perfect mix of resins plus urethane and gives a tough, lasting result for engines and engine accessories.

Interestingly, this product comes at a really affordable price without trading its quality.

What’s more?

The coating products come with engine primer, surface prep, engine metallic, and engine clear. Plus, all its colors have outstanding durability and superb chemical and heat resistance.

Like other products in the VHT engine paint reviews, VHT SP139 dries to touch in 30 minutes. In fact, it dries completely overnight.

This paint is also easy to use, and the color comes out fine.

However, VHT SP139 requires several coats, and the coverage is far from satisfactory. Also, this product is hazardous. Therefore, it can’t be shipped by air or outside the US.

Things to Consider When Buying VHT Engine Paint

When choosing the best VHT engine paint colors, these four factors are what you should consider.

Formulation

Engine paints often have an impact on the environment as per their chemical composition.

While most paints have a fairly similar base composition, the difference comes in terms of the additives.

They usually come with additional stabilizers to ensure a perfect color mixture. Also, some contain more  heat-resistant components to improve the heat resistance, depending on your choice.

Although some brands come with unpleasant (oil-based) compounds, VHT is water-based and environmentally friendly, making them an optimum choice [2].

Application 

Engine paints come either as sprays (for easy application) or as roll-on liquids in regular paint cans [3].

While sprays are quicker and easier to use, roll-on paints’ application takes longer and requires more care. However, paint in cans offers better coverage.

For spray paints, you’ll likely need two cans or more. Just shake for one minute and spray upside down or sideways, depending on the nozzles.

Whereas, for a brush on engine paint, I’d recommend that you apply with a pad or roller (not a brush) to prevent unnecessary marks. Also, you should read the preparation and application guidelines carefully.

Heat Resistance

Most paints can withstand the heat of up to 500 degrees Fahrenheit, while others can withstand much more, up to 2000 degrees Fahrenheit.

The chances are that your car will not produce anything near 20000F, though. Therefore, buying engine paints with such super-high heat resistance isn’t necessary, although it is a plus.

Drying Time

Engine paints come with painting and drying times that should be adhered to. This ensures proper bonding of layers and helps to determine accurate paint cure time to improve surface durability.

While some paints dry quickly (within 30 minutes), others may take a couple of days. Therefore, I’d advise that you check the manufacturer’s instructions to ensure that the chosen VHT paint meets your desired requirements.

Benefits of Engine Enamel Paint

Most car owners go for enamel paints for these four reasons.

Heat Resistance

Engine enamel paints have super-high heat resistance, so they can usually withstand extreme temperatures. They are able to maintain their color and texture at temperatures where other regular metal paints would start to deteriorate.

However, I’d advise you only use these paints on surfaces whose temperatures don’t exceed the paints’ heat threshold.

Aesthetics

These paints not only give you the chance to choose your desired engine block color, but you can also choose your desired finish as well.

Although most enamel paintings work wonders and come out glossy and eye-catching, matte formulations are available too.

Just what you’ve been looking for, right?

Rust Prevention

Another reason why vehicle owners use enamel paints is to make the engine rust-resistant. Since the paints don’t contain iron parts, they act as a barrier to the engine’s rust agents in question.

A well-prepped and painted engine doesn’t rust, and that’s great news for people in the humid region, where rust is more common.

Resale Value

Restoring your baby’s natural shine and gloss adds that extra WOW factor which often impacts its resale value. Should you want to trade your car, painting its engine with an eye-catching color is an effective value-boosting strategy.

How to Use Engine Paints Effectively?

Clean your engine

Before applying the engine paint, wipe down the engine to get rid of dirt and particles. I’d advise you to sand the engine thoroughly using a wire brush as this removes old paint and debris.

Plus, before painting, clean the engine using a water-based degreaser to remove chemicals as well as oil.

Start with high heat enamel paint

Begin painting with high heat enamel to ensure uniformity in top color coating and maximum corrosion resistance.

Spray Application

If you’re using spray applicators, apply the paint using long, sweeping motions. Also, I’d advise that you apply two coats to get the best finish.

Top your work

Apply two more coats, followed by a medium wet coat. Note that fewer thinner coats give a more high-quality finish than heavy coats.

You can then top it up with a clear coat. This helps to seal in everything and keep it looking smooth.

Wear a mask

Remember to wear a face mask applying engine enamel paints. Also, ensure that you work in a well-ventilated area, as this protects your lungs from any inherent harmful chemicals in the paint.

How Do I Prepare My Engine For Painting?

You will most likely want to paint your automobile engine block, especially when rebuilding. This process serves to protect the engine from rust and corrosion as well as clean and make it look attractive.

Engine block painting is best done with the engine completely disassembled.

Did you ask, ‘why’? Right, I’ll tell you.

Painting the engine block with the hoses, cylinder heads, belt-driven components, and intake attached causes improper cleaning as well as overspray.

Improper block cleaning could, in turn, cause the paint to peel in no time due to poor adhesion.

To avoid these issues, you can successfully prepare your engine in these steps;

Disassemble the engine block

Remove the bolt-on parts from your engine

This step includes taking the power steering pump, pulleys, water pump, and air intake manifold off. Also, remove the timing cover, the cylinder heads, and other remaining bolt-on components.

Remove the crankshafts as well as the pistons

Unbolt and remove connecting rods and pistons from the crankshaft. Then, remove these parts from the engine.

Take the main bearing caps off, and then remove the crankshaft from the engine block.

Completely drain the engine fluids

Turn the engine on and let out all the fluids till they stop. Then, force out the remaining fluids using compressed air.

Wipe loose oil with a rag, then scrape off dirt using a scraper or wire brush.

Degrease the automotive engine  

Your engine should be free from oils, grease, and all forms of dirt. The paint won’t adhere to the metals properly if any oil is left on them.

Spray your engine using an aerosol degreaser

Coat your engine with a degreaser spray. Let it soak according to the manufacturer’s instructions.

Rinse the engine completely with clean water

Spray the engine with a garden hose or pressure washer to get rid of the degreaser spray completely.

Get rid of water

After rinsing the engine, blow off water from the engine water an air compressor. This is necessary because the remaining water could cause corrosion, mostly if the engine block has cast iron.

Check for oil or grease

The next step is to confirm that you’ve gotten rid of all the grease and oil from your engine’s exterior. If there are any spots of grease or oil remaining, apply the degrease spray again. Then rinse with water.

Mask the internal engine components

Cover the large areas using newspaper

Cover areas that should not be painted (e.g., the cylinder head mounting surfaces) with a newspaper.

For more strength, use double layers to cover these surfaces and tape the edge of the paper.

Cover the bolt holes and studs

Insert old bolts or a small tape piece to prevent your paint from getting to the threads. In the same manner, wrap the manifold studs using masking tape.

Recheck the engine

Check over the entire engine to ensure you can’t see any openings. Should you spot any, cover with tape or newspaper.

Clean the old and loose paint from the engine’s surface

For the paint to adhere to the engine block properly, you need to get rid of any already loose paint or may come loose soon.

  • Turn the compressor on and attach the media blaster
  • Use the media blaster on your engine
