Restoring an 88 RM250 and had the engine soda blasted to bare metal. Today I sprayed some Rustoleum self etching primer on the engine before using the VHT Engine Enamel paint. The primer looks kind of "soft" to me after about an hour. I don't know whether that's due to it not being fully cured yet or not. I can easily run a finger nail through to the bare metal.
Will this cure to a more scratch resistant finish after a few days? I'm hoping I didn't make a mistake using this primer but the blaster recommended it be done before the paint was applied.
Thoughts?
