Have you ever noticed most of the hot rod/classic car builders use some sort of media blasting for sheet metal and frame stripping? As a individual, I believe in following the tried and true methods of the many professionals that have come before me. Media blasting is not the cheapest method, however it is the most comprehensive way of removing all foreign matter and leaving a pristine surface. Minus the clean-up of residual media, I have found blasting to be the finest bang-for-my-buck method for stripping on my projects.
