1966 Factory V8 Valiant Signet Restoration For My Other Daughter

I can verify there is a difference between production and higher end materials. When I was painting locomotives we had a special hardener made for us so it would cure super fast. It was a challenge for us to get a nice glossy finish from the clear coat because it cured so fast. We had to put it on really heavy and try not to get runs in it.

Southern Polyurethane makes all these different clears. Universal Clear is the high end high solid clear, Production Clear is, well for production shops as it dried fast and hard then Speed Clear which is like you are talking about it sets up in minutes and you can drive the car away in an hour.
