These guys use PPG VP2050 it is quite expensive.CRE is the same PPG product but much cheaper.
I think Mark Worman and many hi end shops also have gone to VP2050 start to finish. 2 or 3 coats will provide
a very thick surface for final blocking. It also dries with a lo luster so you can see any short comings in
your bodywork. Try it on a fender or door to see if it suits you first.
