Most paints, when sprayed properly, are supposed to mimic modern factory applied paint. That means orange peel to some degree. How excessive the peel is will be a factor of air pressure, mix ratios, spray technique, ambient temperature (while spraying), proper hardener for spray temperature, cure temperature, and cure time. I can't speak for your shop, but if you specified a nice flat, peel free surface, it's not unreasonable to expect them to produce that for your money spent. It seems fairly common to see shops color sand and buff the day after a paint job, and while it may be fairly flat at first, some peel can return as solvent comes out of the paint (curing). One good solution is to cut the clear with 1500 a couple of days after paint, and let it sit like that for a couple of days, then finish out with 2000-2500, and buff. That opens the paint up and promotes solvent cure, and in my experience, gives a flat, peel free paint job.
For the least amount of peel straight out of the gun, House of Kolor clears are excellent (and damn easy to run), cost effective, and they have a ton of UV inhibitors. For the money, it's hard to top HOK clears.
The car looks excellent, and I can't wait to see it assembled!:giggedy: Thanks for sharing it with us.
