I Stopped Using Stripper Years Ago, When Going To Bare Metal. I Use A Large Feather Edge Pad, 40 Grit, And A Low Speed. Go Slow And Carefully. I Don't Try To Polish The Metal Clean, Just Remove Most Of The Paint And Then Switch To 80, To Remove The Last Bits Of Paint. A Little Careful Hand Sanding Around The Edges, And You Are Ready To Prep And Prime. I Can Usually Have One Ready To Prime In A Day, With Less Work, No Chemical Contamination, No Fumes, And For Less Money.
