I'm getting ready to epoxy the first panel on the car that is DA sanded. Pretty much everything I've epoxied up till now has been blasted. I *thought* I had the panel ready to go this evening, and began the wipe down process with SPI waterborne WG. I have a couple of sections that I struggled to get to wipe clean, and thought I'd better ask if I need to back up and do something different.
Here's an example. I've wiped this section of the panel down repeatedly by spraying then wiping with Finish Master wipe down towels.
After several passes, I'm still getting what I'm starting to think is rust maybe?
I didn't want to epoxy until I understand what's going on.
The quarter was washed with dawn, then stripped with a 3M clean strip on a 4" angle grinder before 80 grit DA.
Thanks for any and all advice.
