I know I have seen this before but I could not find it in the archives. I just got a brand new front panel for my 57 from a nice guy in North GA and I want to get a primer on it. I will be using Zerorust red oxide for the primer. Should I roughen up the panel as it is? With a orbital sander or will steel wool suffice?

Thanks

Bad rust and worse wiring, but so much fun.
