I wouldn't use base clear. It's water base and a 230SL I have here right now still doesn't have hard paint even though it was done last fall. I would use single stage urethane. That stuff hardens in days and is very durable.

There's a ton of chrome on a 113 plus blacked out areas around the car after it's been painted. 10K would be on the light side because you never know what you will find under all of that paint.

Car should be panel painted; trunk lid, doors, hatch cover, hood, with windshield removed.
