Step 3: Step 2: Strip the frame
Make sure to get all the paint and any rust off the frame. If you decide to sandblast yourself, it can be a laborious process, but you can do it!
*Important: Wear a respirator while sandblasting to prevent silicosis, which is caused any tiny particles (in this case, sand) that get lodged in alveoli. Silicosis is a chronic disease and is no fun. Thanks to "retasker" for reminding me.
