I need to tell you about paint.

Any new car on any mfgrs lot will show orange peel. Articles I've read say it's the additives for UV protection, etc.. that cause the orange peel.
Remember back in the day the plastic filler pieces around bumpers would rot right out from under the paint ? D.O.T. qualified plastics haven't changed so much. Strip all the paint from todays bumper skin and the sun will eat it up. Most of our classics have very little exterior plastic to worry about. We may not let our classic sit out in the sun, acid rain, other elements , day after day either.
Bottom line, consider all the factors, rather than the cost alone.
