Hello, I drive a Golf 3 and these rusts very much like. I am now looking for a reasonable tool (likely also compressed air operated) to remove the maraudous underbody protection in the endangered places. So far I have always used a flex with braid brush. But this is first too hard for me to last, secondly you don’t get anywhere and thirdly this method is not just sheet-protecting Hatz since someone experience with? So as I said: Per compressed air would be optimal, because We have 2 compressors here and a nice compressed air network with a total of 3 tanks. So the supply should not be a problem.
