The respray on this frame was really thick so I started with some Rustoleum paint stripper, scraping off as much paint as possible then sanding with 320, 400, and 600 grit sandpaper (wet and dry). Since these pictures were taking I have done a lot more work with wire brushes and brillo pads. It is so important to have a clean frame when you repaint that spending the extra time to clean off all the old paint will pay in dividends.
