I have some Genuine R98 alloy wheels on my Mini.
As is the case with these, the outer edge of the alloy (the diamond
cut part) has corroded under the lacquer.
Now, none of them have been kerbed, it seems as though water has got
between the 'split rim' and caused all the damage.
I'm about to have them refurbished and want to stop this happening again.
Has anyone sealed the gaps with a thin bead of silicone sealer to stop this happening and does it work????
I have R98s it's a lot of work 15hrs per wheel. I have sanded them down through the
stainless label with a dremel, then using wet & dry paper 400, 800, 1200, paper
keep on going and you get a polished alloy mirror shine. that looks great and stiff fingers
but it worth it.
I too have R98's and mine have started to go under the laquer, I know mine have been kerbed (it was either the wheels against the kerb or the drivers side against a lorry) but the corrosion is not where it has been scraped it is sort of in the middle, between the edge and the pace where the rim meets the rest of the wheel. Is this common? the car is only 3 years old.
caused by inferior lacquer...putting a silicone bead around the gap will not cause it, more likely its stone chips in the lacquer allowing water to ingress. If you are going to split them (recommended) then make sure you torque them back up to the correct spec. We do this as part of our business, and return the wheels back to factory (inc diamond cut lip) for £100 per wheel. PM me if you want more info
....I know silicone sealer will not cause it!
I was going to use the sealer to stop water ingress from inbetween
the two parts of the wheel.
The water gets under the lacquer from underneath, ie from the gap
between the two parts of the wheel. My lacquer is in perfect condition.
I can't see it being down to stone chips in the lacquer.
