My Daytona Coupe (cobra) scratch build

Coming along nicely Mark.!

In my experience those lows and highs are going to be tough to get worked out on the wheel. Someone who is really in tune and been doing it for long may get there, but for the most part hand finishing is likely to be less frustrating (but it can still be pretty frustrating!!)
Off dolly work as Larry said to bring down highs, and you may even look at a ring type dolly - search "donut dolly" and check out the Youtube videos on it.
Heat shrinking too, although I am a long way from being proficient at this on ally...
