Coated aluminum wheels question?

[imported_doug]

Hi, Guys - I know I'm still new to the board, but some of you already know I've been very interested in testing detailing products (paint care only). After reading so many false advertiser claims and users' unsubstantiated opinions, I've gotten even more interested in testing methods. How can we compare one product to another in a truly objective way?

I believe I have found the answer. There are standards (ASTM, ISO) for measuring gloss, and there are laboratory instruments for taking the measurements.

For a brief intro to the methods used, check out http://www.rhopoint.co.uk/instruments/ng-art.html

I've looked into these meters - but they aren't cheap - the "Novo-Gloss" meters start at about $2100. So - I'm looking for creative ways to solve this problem:

1) Anybody know of a company that might rent lab instruments?

2) Anybody know of trade associations or other places where these products might come up for sale used?

3) Anybody want to write me a check for $2K in exchange for my undying appreciation?

These meters would truly allow us to share information in a standard way. This would be a big improvement over merely expressing opinions! I should also add that even these meters aren't a total solution. Some of you have noted one wax makes a finish look "sharper" than another, or one glaze adds more "depth". The definitions of these terms are vague, but i believe we do see differences. It is not clear, however that any meter can measure these effects. Still, I think we would learn a lot. Open to ideas (and contributions!)

man thats some crazy dedication (or jsut craziness) man i can start on a turbo with that money... well i definintley dunno where to get or rent lab stuff nor do i have the expense to donate



but good luck with getting this thing. it can seriously REALLY help alot once used properly with tests

I have access to a gloss meter. Feel free to cut a big panel off your car and send it to me so I can test it. Or you can just fedex the whole car

Steve, LOL



Carguy, you make a good point, though. The meter adds an important, non-subjective measure, though, as you point out, there are some things the meter does not measure.

I have this Porsche from a customer that wants me to "polish" his wheels.
Upon closer inspection, the clear has started to yellow and peel off.
I advised him the clear has to come off and repolish the alumium.

My question is what to use to safely remove the remaining clear?
Has anybody done this?
What's the easiest way to do this, products to use, etc...

TIA,
~Goose.

PS: I'll post some pics tomorrow...

Take the wheels off the car, take the tires off the wheels, then use aircraft stripper. Not a fun task at all.

Another way is too have them soda blasted also alot of work but the end result is awesome.

Only issue with soda blasting them is that it dulls/pits the finish. Either way you have to polish them out.

I thought I've heard of another method(s).
I can't remember what that was.
Thanks guys. I will look at the options I've got...

Media Blasting with glass and/or crushed walnut shells. Was just looking into this recently.

These are the wheels I'm talking about...

I've used aircraft stripper. It does work well, but it's very strong stuff. You have to wear rubber gloves and be careful not to get any on your skin.

You don't really have to dismount the tires if you're careful not to get any on the rubber. I masked off the tires with some real sticky tape. the aircraft stripper sprays on and, in my case, didn't hurt the aluminum at all, but you may want to do a test patch on the back of the wheel.

Let it sit for about 10 minutes, then you can rinse with a hose, while agitating with a soft brush.

I did a set of C5 Corvette wheels and they came out great.... Again, use with caution.
