And heres a arm I did, I didn't sand/bead blast or paint this arm as I'm not looking to restore just preserve a org car. The arms had most of the org coatingon it before I cleaned it off in the parts washer, so the arm was in better than average shape. Next time I will hang the arm and spay it heavy to get the runs as were found from the factory. I have about three spayed coats on this arm. I waited about a 1/2 hour between coats and it will take some time as stated above to cure up good but on my test spays durt wouldn't stick after a few days.
