I've got a cooler from a '67 Shelby and I'd like to restore it. Its in great shape already other then the paint is bad. I've bead blasted it and it looks like it might have been dipped in the semi-gloss black, or whomever painted it really laid it on thick to the point that it ran and collected in the lower parts/areas. So were these in fact shot with a spray gun or possibly dipped. Coverage would most likely be much better if dipped. Thanks for any info!
