I'm thinking of you Jim.
Spent the last two days blocking at 400 on our 72.
My apologies to the professional body guys out there but this **** sucks. About the time you think have it flat another low spot rears its head. Guide coat is great but it can also be a curse.
Back in the day we never used guide coat and went by eye and feel. If a small low spot popped up after paint we would say "Damn, missed that one" and lived with it. :lol:
