05Sleeper- Is this the same car you're taking to Texas? No wax/sealant on the repainted parts for 2-3 months. The Spies-Hecker paint takes a while to finish outgassing, mine took three months the last time they shot anything on the S8 (near the engine so I could smell the outgassing due to the heat from the engine).
Yeah, you can polish right now, but remember to use a polish that does *not* contain wax/sealant. And note that the paint will be a little softer than normal until it's finished curing.
While it's curing, I use Meg's #5. Very user-friendly but you gotta redo it after every wash. Much nicer than the 3M IHG that some people use for this IMO.
