Maybe the baking process had a negative effect on the paint because it was not the heat-resistant type. I have read of guys using engine paint and then baking it on, but maybe that’s not a good idea for regular paint.

I’ve done 5 or 6 planes so far following the same procedure… applying several light coats about 30 minutes apart… and the paint was smooth and hard as a rock by the next day.
