Servus, I have found rust on my car on the underbody. Now I want to eliminate it and see that I prevent the following rust. I have informed myself about so many things, but do not yet know if I have thought about the correct procedure. First I would remove the whole rust as far as it is possible mechanically with steel brush attachments for a cordless drill screwdriver and by grinding. After that I would use rust converter, I have used it for „Fertan-e Thirdly, I would then clean the places and prime them with a 1K epoxy spray, and then I would have used the “normally stable 2X 1K”. I would then treat the primed area with a 2k epoxy spatula and then finally spray with the underbody guard, the “underfloor wax of Nigrin”. Do I do something superfluous or wrong?
