    You may be right about the ABS parts, anyway it's a possibility. I'd think it would look like a fatter/thicker coating than poly or lacquer, and with no clear coat.

    Not sprayed? LOL!

    Well, I've only used Gelcoat once and that was for a boat hull repair. A foot long puncture through the fiberglass hull. After the repair the final surface spray had to be Gelcoat to match the rest of the hull. Came out good, only slightly whiter because the repair was newer that the rest of the hull.

    It's indeed powder coat as Mal told me from the very beginning. Gel coat, as mentioned, is strictly a fiberglass product. It should..(should)..never be used on metal parts like the tank. I'll sand most of the powder coat off both pieces to avoid buildup. The epoxy primer, usually sprayed on to bare metal parts before body work will make a nice transition sealer between the powder and the paint. We'll see how it goes.

    Can you explain how to powder coat ABS?

    I can't, Bill. Never seen it done before. You'd think it would turn into a puddle or at the very least, distort the shape in the baking process, but this one looks great.

    Tuning in as always Larry, and I'm very curious to see how this all goes over the top of powder coat. I've heard many people curse powder coat as a starting point as it's so tough to get rid of, but I'd never considered you could use it as a good base and starting point.

    Sorry to Larry for my earlier posts in this thread. I've deleted them because they are not pertinent to this paint project and I don't want to detract from it.

    Looking forward to watching Larry's magic once more...

    I don't think I saw anything that needed to be deleted, Ed. I find your comments interesting and useful.

    I wasn't sure about the whole powder coat thing either, Pete..but as I soon learned..
