I guess my question is too basic or the answer it too broad. I guess I'm looking for advise on what grit sanding disc(s) would be best to use. As I mentioned before, I tried the chemical stripper but the 2K primer is too hard. Should I concentrate of removing the 2K then go with the chemical or do you think it would be best to just sand it clean? I have a real fear of grinding too much and gouging the sheet metal.
You help would be appreciated.
