Anodizing

[Community]

Anybody know what you can do with aluminum that has been anodized and you want to change color? Powdercoat?

[RiverDave]

You can powdercoat over it, or you can have it stripped then repolished and then annodized.. If it was me I'd powdercoat it.

Anodize can be stripped by the same place that did it the first time. I do not believe you will be able to powder coat over the anodize. Powdercoat requires an electrically conductiove surface, and anodize does not conduct electricity.

Stripping and polishing sounds good.

Easy-off oven cleaner, works well at removing anodizing

You got that backwards.. You can powdercoat just about anything so long as it can stand the oven temperatures. You can't annodize over powdercoat, but you can certainly powdercoat over annodizing. Alot of companies sell powdercoated products that are "treated" for salt water. That's a fancy way of saying that they ran a clear annodize over the part previous to powdercoating. That way if the part is scratched and salt water does make it's way onto the aluminum it won't (or is less likely) corrode the part, and it can be re-powder coated with no issues. If that process isn't done, and saltwater gets "underneath" the powder coat it will corrode the part at a much faster rate becuase it's actually trapped underneath the powdercoat and will more or less rot the part from the inside out. By the time you see the bubble in the powdercoat it's already to late and the part is dimensionally ruined.

Again, if the part has any "fine" details (grooves? lettering etc..) and you are going for a pewter / clear annodize you have to have them repolished.. Those grooves etc.. will take a beating from the repolishing if it's not done at a first rate shop. I'd send them over to Dana (again if it was me) and just have them powdercoated whatever color you want. It'll be cheaper then stripping and repolishing, and annodizing, as well the part will end up being more resistant to the elements in the long run as an extra coating will have been applied.

Often times its cheaper to just but new stuff! Ive seen people spend twice what it would cost them for the same part brand new to restore them by powdercoating or reanodizing just my .02 worth

Thanks for the info. We will be in the keys 4/1 you planning on being out there?

Yup, you can powdercoat just about anything. A buddy of mine ownes a powdercoating shop and he powders all kinds of shit just to see if he can. The oddest thing I've seen him powdercoat so far was the plastic cowling around the radiator on his race car. He did a broken one first to see if it would work (had to change cooking temps and duration a bit) but he powdered a black plastic cowling WHITE! It looked incredible. I would have never believed it if I didn't see it for myself. He powdered the fan shroud on his race car blue and it still is holding up more than 6 months later. If memory serves he had to heat the part in the oven before he shot it, the powder starts to melt right onto the part as he shoots it, then it's back in the oven to finish it off, pretty freekin cool if you ask me. I had always thought it had to be conductive too. Apparently not!

As of right now I'm not sure what the plan is.. Things are pretty financially fuct for me right now as I lost my ass on CEM, and am currently in the middle of a new start up company.. (Incidentally the new start up is again in the boating related biz.. apparently I didn't learn my lesson on the first one :D)
