I am a homowner of an older house that has the old large hot water radiators. I love the way they look in the house and do not with to cover them with radiator covers. The problem is all of them have been covered with countless coats of what appers to be latex paint. I would like to refinish them. Is there a special paint that i couls use that would prevent blistering and be able to withstand the increased temperature. Or could i have them sandblasted and then powdercoated.
