No — Motor Coater does not need to be heat cured. It cures simply by ambient air, making it one of the easiest engine coatings to apply.
If you want to speed up the cure, you can heat cycle it — place the painted piece in the sun for one hour, then move it to the shade for one hour, and repeat. This is not required, but it can accelerate the cure when needed.
💡 Pro Tip
If you choose to heat cycle Motor Coater, wait a minimum of 12 hours after the final coat before starting the heat cycling process. Rushing the initial break-in cure can compromise the finish.
