Might be a bit late for this post but here's my before and after interior pictures after painting with PPG Industrial Paint. I used the right inside side vent cover plate (it didn't look like it was to faded) and had it a scanned and a custom mix done. I didn't get a formula for the paint, It's just labeled Chevy Gray!. I added 1 oz of xylene to the paint in the spray cup and mixed it up and painted in my garage last winter. A couple of ceramic heaters overnight under the truck covered with a parachute tent to get the metal nice and warm and I think it looks pretty good.
I took the left over remaining paint and had the shop fill 12 rattle cans enough to do a couple of more trucks!
Cheers
