As most know, you will get the best finish when you spray metallic coatings because the process of spraying allows the metallic pigments in the Motor Coater to float to the surface creating the metallic sparkle. That said, spraying Motor Coater is not always an option, and we get that. An extremely popular brushing technique for brushing metallic coatings is to brush out the Motor Coater, let the coat cure for a few minutes, then lightly brush the surface again in one direction which will help float the metallic pigments to the surface giving you a nice metallic sparkle finish. As with all painting techniques, practice makes perfect.
To apply Motor Coater with a spray gun, do I reduce, how much, and with what?
When spraying Motor Coater, spray pressures of 35-45 psi (250-330kpa) for siphon/pot guns and 25-35psi (170-250kpa) for gravity/top container guns are recommended. Thinning of 5-10% is normally adequate and use KBS #1 Thinner or Xylene only which are designed to be slower evaporating solvents which work extremely well with Motor Coater.
If you want to speed the cure of Motor Coater, you can heat cycle it which means put the painted piece in the sun for an hour and then in the shade for an hour and repeat. This is not required, but it can speed the cure of Motor Coater if that is desired. Please only do this after an initial break-in cure time period of 12 hours.
Motor Coater is an ideal paint for brake calipers which will make your calipers pop and stand out. Because Motor Coater is glossy and durable, it makes cleaning your calipers much easier. Motor Coater is good to 450F which is more than enough for calipers.

Looking to brush Motor Coater and wanted to know what type of thinner is needed?
When brushing Motor Coater, thinning is not generally required, but if needed, 5-10% is normally adequate. Use KBS #1 Thinner or Xylene only, which is a slow evaporating solvent.
PRO TIP: When brushing Motor Coater, please brush it on in thin coats and let the brush marks flow out. If you brush over an area over and over again forcing the solvents out, you run the risk of the brush marks not flowing out as well they are designed to flow out.
I will be coating my marine engine with Motor Coater, but have some rust spots on the iron die-cast manifold. How would you recommend I prepare this spot before applying the Motor Coater Engine Paint?
It would be best to clean the entire marine engine with KBS Klean. Then, you can treat the rust spots with RustBlast. After you have cleaned the engine and treated the rust spots with RustBlast, then you will paint the marine engine with Motor Coater.
