I have a 1952 PD4103 which has the original Trailways anodized aluminum siding. See the picture in my avatar. It's in pretty rough shape, and needs to have something done to it to make it look better. I considered paint, but that just doesn't ring my chimes. I also considered sanding off the anodization and having it redone.... New siding is cheaper, LOL! Then came Christmas. Some nice soul bought me a powder coating set up. I won't mention names, but I work for them! now the question comes: Can I put a translucent or metallic powder coat over the existing anodizing or does it all still need to be stripped off with a sander and acid, then a chromate bath to assure adhesion? I am going to build an oven with plywood sides, aluminum lining and an insulation layer. I plan on using 6 - 250 watt infrared bubs and the thermostat out of an electric oven. I am even open to clear coating the aluminum after the color, using a Diamond or Pearl clear coat. Pros? Cons? Thoughts? Stupid Idea? Here are the colors I'd like to use: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=370257184142&ssPageName=STRK:MEWAX:IT http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320601433255&ssPageName=STRK:MEWAX:IT | ||

letter 41055 Powder coating anodized aluminum parts ++++++ I have thousands of small black anodized aluminum parts that I wish to powder coat w/o first stripping. Is there any problem w/ compatibility or significantly diminished adhesion? Chuck DeWitt electronics - Hamilton, MT, USA ++++++ There is no 100% answer. You can paint over sulfuric anodized parts in most cases. In a few, dye might cause a problem. there are several paints that do not like chromate sealed or chromic acid anodizing. Seal does not make a lot of difference unless the parts are quite old, then sealing helps. Wait a day after anodizing to paint as your powder coat cure temp might cause a lot of water outgassing. I think that unsealed paints better, but I have read several opinions to the contrary. Best is what works for you. James Watts - Navarre, Florida July 31, 2008 Is it possible or is there a specific process to anodize aluminum pre-bend and drilling without molecular failure and eventual flaking off of the finish? Thomas Babcock Bozeman, MT, USA contact button August 2, 2008 Hi, Thomas. No, I don't think so. Anodizing is a very hard and brittle aluminum oxide ceramic coating. You can't significantly bend it without it badly cracking. If it's going to be bent, chromate conversion coating sounds like a better choice. Regards, | ||

Thanks George. I read that also. I also read about 10 other pages from my Google search, unfortunately the answers went from "absolutely not" to "Of Course, that's the preferred method!" | ||

Dallas - Perhaps trying it on a small piece first, before attempting the entire coach? FYI, there were a couple of GM's at Arcadia (an '04 and an '06) that had the anodized aluminum painted. On both coaches, the color match was so good you could not tell that it was paint until you got right up close to it. One of the owners told me all he did was take the fuel filler door into an industrial paint supplier and asked the guy to match the color. So, even tho paint's not high on your agenda, you might give it another thought.? FWIW & HTH. . .  | ||

RJ, I thought long and hard about using paint, but in all actuality, I'm lousy at automotive painting, besides powder coating has a much longer life span and is much more forgiving. Some of the types I looked at run quite a bit less than $18/lb and cover 70-80 sq. ft. per pound I plan on getting a bit of experience with the powder coat first. We have a bunch of stuff around here that could stand sprucing up and would benefit from even a bad powder coating job. LOL. One thing would be my little JD lawn tractor... A girl who worked here a couple of years ago decided that it could go through a pile of trees and brush. It no longer has a hood so I was going to use a piece of ceiling from an MCI 9 and build one for it... Think John Deere Green with FLAMES! hahahahahahaha! (Maybe even a chrome stack and a flapper)! | ||

Dallas dont think for a moments notice that powder coating is bullet proof. I used to have my race car chassis's done and it WILL chip. You can't just fill it in like you can paint. | ||

Yeah, I know, but it's better than the alternative, which is my painting! | ||

You could practice spraying paint as well. I could help when there. heck we could practice on my bus, I was thinking something along the lines of peter Max's work. | ||

I can handle a rattle can with the best of them! I even have one of those fancy handle doo-dads so your finger doesn't get tired pushing the button! | ||

if you can spray paint with a rattle can correctly then you are well advanced enough to take on a real gun even HVLP | ||

I agree with FOO HORSE.. If you can get that stuff to flow, you can defin-at-ly use a HVLP gun!! The best one I have bought was from of all places Harbor Freight! I have one that was over $200 and the,on sale,2 piece kit for $40 does a better job. Yes I keep them cleaned and ready to use too. Gomer | ||

Dallas, There was a post on the Wanderlodge board I think about removing anodizing. It comes off with Easy Off oven cleaner. TOM | ||

Tom, You have never dealt with the anodizing on the old GM Silversides. I have used Easy-off, Straight Lye, Muriatic Acid, Pecan Shell blasting, and wet/dry sand paper. This layer is hard and thick! According to much that I've read, when powder coating, leaving the anodization on is a preferred method. I have a couple of old pieces of siding I got from another bus that I will try different methods of coating. that is once I get the oven built and the current projects done. | ||

Dallas, At least you are not having to fix a Wanderlodge that was rewired by Doc Brown's (Back to the Future) protegee! I figure we're about even. LOL! You should buy my MCI; then you wouldn't have to deal with the aluminum & I would have enough money the rewire my 'Bird! Give Cat our best belated birthday wishes.

Tom, I like your MCI, it's a nice looking bus. I have worked on a few Wanderlodges of the 70's vintage and they were pretty well set up. Then I had to do some genset work on an early 90's model and it was a nightmare just trying to follow the poor diagrams and actually trace wiring. BTW, if I was rich, I'd buy your MCI in a second! | ||
