I have a '63 shasta and have started to polish the z stripe. I plan to paint the trailer after the stripe is polished. I have managed to get the actual stripe pretty shiny using a scouring disk on my electric drill and mother's polish. But there is still black smeared above and below the stripe. When I use more mother's to try to get this area clean, I just seem to produce more black. It seems never-ending! I am really worried that the residue will keep my paint above and below the stripe from sticking. Should I be using a different cleaner to clean this area?
The black stuff is aluminum oxidation the mothers is lifting from the surface. There is a solvent auto painters use to wipe down the surface to be painted commonly called "Prep Solv" It can be purchased at any automotive store with paint and body supplies. www.carid.com/universal-paint/dupli-color-specialty-product-4014584.html It removes all oils, waxes, and contaminates on the surface for painting. It flash dries but you should give a few wipes with clean dry rag after application.
I'm sure there are others on the site with great ideas too. Enjoy the site and again welcome. Soup
