A friend has a 1976 BMW 2002 in fair to good cond but the paint is in ruff shape is this a clear or single stage? One layer is peeling up a very fine layer could this be a layer of paint and if so is the very ruff looking next layer fixable. He sanded the top layer off a little on the roof cause it looked better. It looks like a clear peeling but it does look like it has color that is why I think it is salvageable and one stage. I cant get pictures easily. At the time that he sanded it down you could peel it. Also if it is a clear wich I dont think it is can I blend in the good and bad parts and shine it up more? Thanx for any info
