Rick,
The "waterproof fiber reinforced bondo typ stuff" goes by many names.
I always call it tiger hair, but the can I have now is called kitty hair.
But that is what I filled in the holes with, after backing them up with green rod to keep it from falling in the floor of the car.
But the small pits I filled in with my mixture.
All of it will either be covered by the windshield or the stainless around it so it doesnt have to be pretty.
Tomorrow night when I get home from work, if I'm not too tired,
I will sand it down a little and spray the epoxy primer on, then maybe Tuesday night I will put the windshield back in.
The Chevelle is progressing nicely, now that I have some motivation.
Phil
