Apologies if this has been discussed before, but it appears that a number of parts on my '71 convertible were originally dipped in paint instead of sprayed. Some of these parts, like the straps for the gas tank, are quite long, making it impractical to dip them due to the amount of wasted paint left over. A technique I heard about was to seal off one end of a PVC or some other water tight pipe, fill the pipe mostly with water, and then float black oil based paint on the top. The part is then dipped through the paint and pulled back out. The theory is that the paint coats the part on the way in, and the paint adheres to the part as it is dipped through the water. Has anybody tried this?
