This is a heads up for others considering on coating the insides of their motors. The directions for Glyptal paint state “If you bake” the part after painting, leaving someone to believe it’s optional to use it on engines without taking that step. If you don’t bake it it you may find yourself worse off than before. The reason baking as an option is Glyptal’s original use was for insulating electrical equipment. Motor windings and other components aren’t faced with the heat/chemical combination found in an engine. Plus heating electrical equipment to 250°f isn’t reccomended.
I don’t know if I’m-heat treated Glyptal would fail, but heating metal parts opens any pores that draw the paint into them and releases gasses trapped under the painted surface.
I set one of the heating elements a bit too close to the baffle and it discolored it a bit, but no one will see it
