Carbone Lorraine pads won't wreck your wheels, this is down to the sintered material being left on the wheels surface too long, after all it is mostly metallic and will oxidise. Two things you can do:
1) wipe your wheels over with a bumper silicone or similar after cleaning, this will make the dust remain clear of the painted surface.
2) Ensure you hose the wheels off once a week, which most people do anyway, it is important to remember you are fitting out and out race pads to your road car.
In racing your wheels would be changed and cleaned every few hours and is not a consideration Carbone Lorraine take into account when developing the product. As Batman seems to know all too well, this is a minor issue for the reward this product gives you first press. I have never had a set back, and never sold a different brand to a customer who has had Carbone Lorraine in the past. I think it's time you converted to Carbone!
