I have a sunroom addition to my house. I just had new windows installed to replace the cheezy stormwindows that were the only windows in the room. Also added a window AC to cool the room in the summer when we use it from time to time. The room has electric baseboard/wall heaters already installed. The covers are a little rusty and we want to eventually paint the room. My question is...What should I use to paint the Heater Covers? Obviously latax whould be a bad Idea? Thoughts?
