Have old beater 86 Volvo (aka Swedish Brick that you can't kill with an elephant gun) I would like to get an inexpensive paint job on ...a la Maaco, etc. Is dark gray and apparently had some sort of clearcoat on top that has peeled off in patches making it terminally ugly. Is it worth it doing something to get the rest of the overcoat off before going to the paint guys. I will talk to them but they are monetarily motivated so not sure about the honesty of the answer. Would chemical removal work or is it sanding only and what would I use (machine? grit? etc.). This is my second car that goes in snow in Denver when the MGB isn't an attractive alternative and hauls stuff on the roof, etc. etc.
