We blasted our "Howie" 1946 Chevy 3/4 ton cab on the weekend... We have 2 problems...
1-Small hole about the diameter of your pinky finger near the hole where the windhshield wiper goes
2-Hole of about 3 inches long and about 1/16 inche wide running in the channel where the windshield sits in near the roof of the cab.
Any suggestions as to what to do with these?
