Engine Paint Buying Guide

Application of an engine paint takes just minutes and can transform the engine bay. Whilst most enthusiasts match the factory paint, there is nothing stopping you spraying the engine block and other accessories multiple different colors.

To help you make an informed buying decision, we have produced the below guide regarding engine paints.

What are the Benefits

The main benefit for investing into the a quality engine paint is the customization of the engine bay. There is no limitation to the colors you can choose and you can completely transform the engine bay to suit your requirements.

Once correctly applied, the engine paint will help prevent corrosion and withstand high levels of humidity. It also helps improve the resale value of your vehicle because no one likes to see rust under the hood.

If you paint the engine block with a dark paint, it can help with heat dissipation. This results in the engine cooling down faster once switched off, which can be very beneficial for some vehicles.

Heat Resistance

We highly recommend that you use an engine paint that can withstand up to 500 degrees Fahrenheit. There are many that can withstand over 1,000 degrees Fahrenheit but they cost far more and are not necessary for most applications.

Colour Matching

Matching the engine paint with your paintwork or the brake caliper paint is very popular. Many manufacturers state that their paint is an OEM match or factory color. However, the likelihood of a 100% match is highly unlikely due to the UV ray damage, multiple car washes and age.


Most engine paints use a combination of urethane and ceramic resins. Some brands will also include additional additives that effect the finish or increase the heat resistance.

Some formulas can be brushed or sprayed onto the engine block. Choosing between the two is dependent upon your personal preferences. Spraying the surface is less time consuming but it can produce a lot of overspray. This can be an issue if you haven’t thoroughly covered up all the remain components.

Preparation of the Surface

Before applying any engine paint to the block or other accessories, the surface needs to be thoroughly prepared. Once completely cool, you will want to strip as many components from the engine and wrap up anything that is left connected.

It is advised to use an engine degreaser to remove any grease or other oils and remove loose debris using a wire brush. If the surface has been previous painted, it’s highly recommended to remove the paint using a fine grit paper.

Depending upon the engine paint, you may require a primer beforehand for the best finish. To ensure that the application is long lasting, it’s recommended to apply multiple thin coats and allow the paint to dry according the specification.

Failing to allow the paint to dry will result in blistering, peeling or cracking of the paint once its subject to high temperatures.


Using a quality engine paint that can with standard high temperatures and fluids can transform the engine bay. Most formulas can be applied by a spray can but there are many brush paints that may be easier to apply to certain engine components.

All of our recommendations are suited to a range of budgets and offer a range of OEM exact match colours. Standard paints may be cheaper but they will not be able to withstand the high temperatures of the engine block.
