does anyone know if enamel will melt if you use it to paint your 2-stroke exhaust? I was thinking of repainting my pipe cause it looks pretty ratty and wanted it to have a glossy kinda look but i just wanted to stick w/ black. would it be safer to just use spray paint? also do you think it would matter if i sanded off the old paint or not to protect it from rust. I wasn't planning on removing the old coat but if i need to than i will.
