4 years ago I had conserved the underbody with Mike Sanders on both vehicles: in advance rust as well as it goes away and protected on thin sheets (wheel box) with 2K primer – on top of the grease, on the thick metal parts on the underbody, like chassis only the grease on it. Per vehicle about 4-5kg of fat has been distributed. Unfortunately the result is that in the splash water area the grease has either been rinsed off or what is worse it is submerged by moisture and it ro So there are always small grease spots on the bottom of the Mike Sanders fat. Only in the places where no splashing water penetrates the fat lies clean and full on it and even small rust spots are not rusting any further there 100%, the wheel boxes had now freed from the fat and there could have been the fat. Will the carriers and also the chassis carriers rust up and also take the transmission and the chassis out around there. Only how should the rust protection be carried out, so that the whole 10 years still lasts (vehicles are 2000/2004). Derusting as well as possible, however, does not always go blank but there are individual rust roots. Either I take Brunox Epoxy and brush the areas, however, is in the bag, which dries this stuff very slowly (months) and is therefore not suitable for an additional protection structure, especially in the splash water area t really or not so tragic? After one day it feels dry. I actually wanted to spray on the Brunox rust protection 2K-epoxy primer and 2K clear varnish, alternatively hammerite brush. Afterwards spray rope grease on it. Does anyone have experiences what holds and what does not hold?
