So I got the top side sprayed grey. I thought about the original off white per the factory, but thought it looked better with the Grey that whoever else painted it did it with. Picked a Chevy Grey and sprayed it last Saturday morning.
Windshield guy came today and installed a brand new window and seal.
Finally before the sun ran away tonight, I sprayed the crap out of the new metal with rust check. Note small dark puddles under the rockers.
