man I'd do that but shipping will rape me and I dont feel like takin out my tires

Rick I have talked to a lot of people about this situation and have done 8 rims so far , That�s why it took me so long to offer this Group Buy , I always want to make sure I can do something before I offer it . I was assured by many people that there aren�t any problems with doing rims. If there was I guess neither have I seen it, or was told by anyone. Maybe you can send me a PM so you can advise me more on this issue?

Basically, outgassing turns a heat treated aluminum wheel into buttersoft aluminum that can bend or crack on the smallest of potholes. You can get by using a UV cure lamp and some low cure temp powders.

What you want to avoid is any oven cure temp that heats the wheel all the way through at a temp high enough to change the metal structure (different temps for forged vs. billet).

darn i wish i had some extra money right now, i wanna have the insides of my st-200 spokes done:(

Are the people who are interested reading the warnings and doing some research?

Hey Josh:

I don't know why anyone is jumping on you about rims. I have done a ton of rims in all sorts of substrates... including alum & alloy's. The curing temps of 400F will not cause any damage to the rims.
Outgassing is another issue.
I outgass casted items only. To outgass, I prebake the casted item about 25F - 50F degrees higher & 20 minutes longer than the recomended cure schedule of the powder I am using. I do warn my customers that "Although I prebake to prevent & limit outgassing. It is not always 100% effective. And that I cannot be held responsible for additional outgassing"
So powder away!
Good Luck
Bob

Who is Bob and why is he an authority on this?

i would love to have mine done but i already painted mine plus you said no 2 tone

what about aftermarket wheels that come powdercoated from the manufacturer. how do they do it?

I haven't seen too many wheels that are actually powdered from the factory, but the process of using UV curing or low temp curing powders would be my guess as neither one of those options heats the rim much.

Rick

I will add my uneducated .02 here.

I had my 93 SHO rims powdered coated in 00. I had 0 problems with the rims and they looked beautiful.

Quite a few fellow SHO guys have done the same, and its a big thing in the L community as well.

As with anything there are associated risks.

I guess i should have mentioned i have a UV curing system .

BTW, pass this message on to Bob:

Prebaking at higher temps only eliminates the outgassing making bubbles in the coating. It does not eliminate the metalurlogical change that happens that removes and/or alters aluminum heat treating at those prebake or cure temperatures in a regular curing oven! In fact, it makes it worse!

Powdercoatman, you will be O.K. coating rims if you use a UV cure system and/or low temp curing powder. Do not take the chance that Bob does with his customers' lives!!!

The people who say that say baking aluminum aluminum/alloy rims is dangerous are idiots .I *am* an engineer, and molecular reorganization (annealing) only begins to occur at about half the melting temperature of the material. Since aluminum melts at 1220.58 �°F, you can divide that by 2 and see that you'd have to be curing powdercoat at over 600 degrees before affecting the strength of the aluminum. Alloys of aluminum typically mix in materials with even higher temps, so they are also no problem.

But you folks who think that powdercoating rims damages them...you go right ahead and think that, and send your customers over to "Crazy SuperMatty" and I'll gladly suck up your lost profits.

I didn't say any of this , jsut something I asked about, so I pasted the info here .
