I am currently having a visible pump painted with powder coat paints. I was quoted painting with 2 colors at $200. I left the frame of the pump assembled so it might cost more if totally disassembled. I was told that polurethane paints were the best spray-on paints but was quoted $200 for one quart of red paint. The powdercoating business told me to use hi-temp liquid metal paste (contains aluminum) to fill rust pits, etc. The pump was straight but had some rusting. I sanded the putty after filling. I have no experience with body work but I think the red parts (sheet metal) look great. The green parts will be completed this week. I can offer no side-by-side comparison of paint products but I think my pump is going to look very good and have a durable finish at a very reasonable price.
