Hey guys, Got my 34 Ford coupe project getting close to paint time, but I just encountered some really hard, tough paint thats on the hood panels. Haven't run into this coating anywhere else on the body but this is some tough stuff. Looks as if it's really pretty old probably so I thought I would just sand or grind it off while doing some small body work areas on the hood panels. You can hardly scratch this stuff with a 60 grit angle grinder ! Guess its a pretty old epoxy coating ? finding some body filler or glaze work under some of it where I did a little repair work. Besides the spots that I needed to grind down to metal and work out, the rest of the hood looks really nice. Would it be advisable to, or not to, consider just scuffing it up and recoat it all with fresh epoxy when I prime the repaired spots ? Or should I try to completely strip this material off and start fresh ? The small areas that I'm repairing actually had small "spider cracks" around them where this old epoxy cracked. Thats where I found out how hard it was to grind these spots down to bare metal... Thanks for your advice..
