My painted cam covers took about a week to dry, the heat of the engine bay will cure the paint. You might smell the paint after the engine is warm, it's normal.
a week...holy crap!!! and in that week of wet paint, you never got any bugs, dirt, or anything else latched onto that paint.
I've never heard of a paint that takes a week to dry. I think even the bottles of engine paint recommend something like 10-15 minutes between applications and 24 hours to completely dry.
