Black coating on Mk2 rims

[Dieter H. Marschall]

Hello everybody,

As I bought a used set of Mk2 rims, I would like to refurbish them. The problem is that partly the old, black coating peels off. So I would like to remove the old coating totally, but I do not know how.

I have tried rotating wire brushes, chemical strippers etc., but in vain.

What can you recommend? I do not want to have them sandblasted, as afterwards it is very difficult to get the polished parts into the old, nicley polished state again.

Kind regards, Dieter.

P.S.: As you can see the days over here are getting shorter and colder, too. So one has to think of a "pasttime"

Dieter have a look on page 3 as I asked a similar question about the refurb of the black paint. I'm afraid it's pretty time consuming and takes loads of patience and time.

I did however remove all the old paint from my spare using a good quality paint stripper, just avoid getting it all over the shiny bits and don't leave it on to long. The shinny bits will polish up though with good metal polish

See Page 3

worried about your alloy wheels corroding?

Hello,

does a paint stripper really take the plastic coating away? Under this coating a lot of aluminium oxide has built up making the coating bumpy and peel off.

A rotating wire brush was of no help so far.

Kind regards, Dieter.

Dieter the black plastic bits are actually enamel paint, and should come of easy.

Once removed clean all the stripper away with soap detergent water.

Sand carefully with very fine sand paper.

You can do 2 things. Mask the wheel off and use etch primer 2 x coats and then a nice shiny black. Problem is the masking is a nightmare and takes forever.

You can hand paint it with really good quality fine brush using hand primer and good enamel paint on top. Make sure the primer and enamel are compatible, to avoid reaction.

I have done this with mine, although I may in the future, get a guy who undertakes air brush work to do it for me. These guys do all the fancy work on motor bike tanks and fancy trucks

Hi Dieter, the best paintstripper for that job is Nitromors, it should be available in Germany, I used it to re-furb mine and it works a treat, it works quickly so is unlikely to damage the shiny bits, it will strip both laquer and all paints. As Moraystag says, after working it must be neutralised with warm soapy water, it WILL burn your fingers a bit, but what's a little pain in when it's for your Stag ? Martin.

Martin did you hand paint yours or mask them off. I completely lost the plot trying to mask mine off as the masking tape just would'nt take a hold, not sure if it was to old.

What do you think of the air brush idea??

Hiya, I very much do like the airbrush idea, but wanted to do it myself. Firstly I polished the rims, maskedthem off andspray painted the whole wheel. The next step was towet and dry the "spokes" and polish them, easy enough to do using a small block as all the faces are flat. The best paint is Hammerite with their own non-ferrous primer, sticks like glue and doesn't chip. Martin.

@ Martin:

I tried a powerful paint stripper, but the "Paint" refused to come off. The paint does not even crinkle. From that fact and from the fact that the parts, which peel off due to the alumnium oxide, come off in whole flakes, I have the suspicion that here we do have a sort of plastic coating and no black paint.

Kind regards, Dieter.

The black 'paint' on my alloys seemed to ba a sort of rubbery substance. I used many applications of Nitromors to get it off. It Doesn't bubble up but it seems to weaken the surface enough for you to scrape it off. I have done one and a half wheels so far over the last 12 months!

Dieter, I think the only safe thing to do now is see if you can find someone that do's SODA Blasting. It is pretty good and will not mark glass or platic trim. Should be good for shiny wheels

I have seen it used in the oil industry and it is good, try a search on the web type in

soda blasters. Screw fix uk do one and it's not to expensive to buy, thinking of buying one myself for doing underneath my car
