Hi folks, I would really appreciate some advice on how to best get this fender ready for SPI epoxy. A quick history, the fender is sound however had a ton of surface rust. After going over it with 80 grit on a D/A, any where the surface rust had been looked "stained", which I believe is rust down in small pits. I decided to invest in a small HF pot blaster and 40/80 crushed glass from Northern Tool, and practiced on an old door to make sure I avoided warping anything. Ended up using about 60 psi and making sure to keep tip at an angle and not linger too long in one place.
I've been very happy with the blaster and the crushed glass media, but there are still places that have a "shadow". I realize there's pitting there so it will look slightly different, but my fear is these rust pits are so small that my media isn't getting in there very well. There's a place about 2 hours away that sells quality blast media for $9.00 a bag (www.blast-it-all.com) and they have a 70/200 crushed glass.
Would it be worth the drive to pick up this finer media and try going over some of these spots again? Or am I over thinking this (tend to do that).
Any and all advice is greatly appreciated. Any thoughts on what to put over the epoxy to fill the pitting would also be much appreciated.
Thanks,
Robbie
