My long-time (over thirty years) painter and friend, that painted the Heritage wheels and every dragster, street car, eighteen wheelers, tag-along trailers, and motorcycles that I have had done over that period of time is Danny Griner- Danny Griner Paint and Body in nearby Burkburnett, Texas. I think his skill and expertise is probably more responsible for the results you see, than the brand and type of paint, although he does use the best available. I feel sure he would tell you what he used, if you care to call him. Danny let the GT Guys use his lift and facility when they serviced my Heritage and installed the Whipple supercharger.
My Lola T70 is shown here in a part of his facility.
Cheers,
Eddie
