Can I Make Motor Coater An Aerosol?

Q: What should I thin Motor Coater with for spraying?

Motor Coater should be reduced 30–40% with KBS #1 Thinner or xylene for best atomization and flow when sprayed through a Preval Sprayer or conventional spray gun.

Q: Will sprayed Motor Coater be as durable as brushed application?

Yes. Sprayed Motor Coater provides the same heat resistance, chemical resistance, and long-term durability as brushed application when properly thinned and applied.

Motor Coater Engine Paint is designed to brush on smoothly, but it can also be converted into a professional-quality engine paint aerosol for easy spray application. Many Motor Coater colors are available pre-packaged in aerosol cans — and every color can be spray-applied using a simple thinning method with a Preval Sprayer Kit.

To create your own engine paint aerosol, reduce Motor Coater 30–40% with KBS #1 Thinner or xylene, then spray through a Preval Sprayer Kit. The result is the same smooth, durable, heat-resistant finish as a factory aerosol — in any Motor Coater color you choose.

This method is ideal for custom colors, small touch-ups, or when your preferred shade is not available in a ready-to-use spray can.

Quick Method — Motor Coater as Aerosol: Reduce Motor Coater 30–40% with KBS #1 Thinner or xylene → load into Preval Sprayer → spray like any aerosol can.

Frequently Asked Questions — Motor Coater as Aerosol

Can Motor Coater be sprayed if my color is not available in an aerosol?

Yes. Any Motor Coater color can be converted to an aerosol spray using a Preval Sprayer Kit. Reduce the paint 30–40% with KBS #1 Thinner or xylene and spray normally. This gives you full access to the entire Motor Coater color range in spray form.

What should I thin Motor Coater with for spraying?

Motor Coater should be reduced 30–40% with KBS #1 Thinner or xylene for best atomization and flow when sprayed through a Preval Sprayer or conventional spray gun. Thinning too little can clog the sprayer; thinning too much can reduce film build and durability.

Will sprayed Motor Coater be as durable as brushed application?

Yes. Sprayed Motor Coater provides the same heat resistance, chemical resistance, and long-term durability as brushed application when properly thinned and applied. Multiple thin coats are recommended over one heavy coat for the best finish.

Do I need primer before using Motor Coater?

Motor Coater can be applied directly to properly prepared metal. For maximum adhesion on bare steel, use KBS Clean and RustBlast following the Motor Coater application directions before painting.
