I haven't posted in a while but was wondering if someone out there could give me some ideas on polishing the upper and lower side mouldings on my 1972 C-10. They are all in very good shape as far as dents and dings but are very dirty and dull. I have bought several polishes from the auto parts store but they are still very dull when I am done. I was considering buying a buffing wheel for my bench grinder but really don't know that much about them. Any suggestions? Thanks in advance.
