Sanding Discs- Scratch the metal?
So I am in the process of prepping my under hood area for a fresh coat of paint. Here's my question- do the abrasive sanding discs that go on the angle grinders work well and if so, I am concerned that they may scratch the bare metal. Has anyone used these with success? Should I worry about taking off all the paint or does it provide better coating on bare metal. I will be using the eastwood under hood ceramic paint. Thanks!
