2k primer lifting problem..
Using 2K Primer on a NEW 68 Camaro rear spoiler.. When I go to block sand the spoiler I've been getting 2 or 3 spots that the primer actually lifts and didnt adhere. I block sand the spoiler down and feather out the spots that lifted and spray again.
Then I'll get at least 1 spot that will lift again and in a different spot. The spots are usually 1" or 2" in Diameter. It's happened 4 or 5 times now and I'm getting stumped on this one.
