Stripping and Blasting
DIY sand blasting equipment and technique
Sand blasting is an efficient way to remove surface rust and thin paint especially from inaccessible areas. With a 14cfm compressor, pressurised sandblaster and patience it's possible to blast whole chassis, body shells, and even thin outer body panels.
The page describes the equipment and grit required, and includes all the tips I could think of after getting the system working nicely.
Paint stripping car panels
There's no need to start from bare metal if the existing paint is in good condition. But if you do decide to start from scratch using mechanical methods you might put too much heat into the panels causing distortion.
On this page I've combined strip and clean discs with paint stripper to reduce the heat input and increase the speed of paint stripping.
