I haven't been able to find a definitive answer as to the process for painting over EDP. I will use the lacquer thinner on a rag test to make sure it's good, and if it is, how should I prep? Ideally, I would like to scuff with the appropriate grit, spray epoxy 1:1:1, then straight to base/clear. But in my experience, EDP is thin and I will sand through it in spots no matter what grit I use. So what grit should I use in this approach?
