Re: Can I clear coat this or is it too far gone?
If the current clear is thin or the flakes are exposed don't sand on it, if you do the finish can start to look blotchy and uneven.
Use YD's method of spraying a cheap rattle can clear on a small part of the worst area, this will give you an idea of what a better clear will look like. You can just wipe it off with acetone after you see if you like it.
