Hello, if we were here in the Mercedes W210/S211 forum, the users would laugh to themselves But luxury problems are something nice, right? -My `99 V70 TDI is the rustiest one I know, because he has a few small spots, among others in the rear wheel boxes. To those I have put to rest today with sandblasting gun and 2K epoxy resin primer. Mostly I only had to radiate loose lacquer layers and zinc oxide away. In two places, where to strengthen the rear seat. On the outside these sheets are pointed, but it was only possible with sandblasting fast+grundlich. I used about 10 kg. Beam material. The thick, closed porous layer EP819 is in principle already quite alone “viable” in terms of corrosion protection, nevertheless I make still a layer of plastic body (Teroson Record or so) on it, and then for the optics car color or the next best dark blue colour, which my paint rack gives. Then come the Radha wessels back in, and I don’t need to waste any more thought on rust in the wheelboxes the next 2-3 winters. Greetings Chris
