I need to strip the paint from the cowl assembly of my Model A. I have patched all the sections that need it and flap-disked all the accessible surfaces, but there are still many nooks and crannies that need to be stripped. I have considered using paint stripper, but would like to try glass beads if appropriate. I have only ever used coal slag (black beauty) in my blaster, but it is harsh, and does not leave a clean smooth surface. Are glass beads or crushed glass the right choice, or should I try the stripper?
