Ok,I am still a newbie here, but before becoming a teacher worked for several years in my fathers garage, though have to admit my trainings mostly shade tree and always came with my infamous 5 feet or 5 second warrenty, whichever came first. I have my truck to frame, and have been researching and everything involved. This por 15 appears to be some kinda wonder stuff at stopping rust. Now this truck means more to me than my ol dog, so this project is a one time deal. The truck will be a driver but it is my grandfathers truck so I want a new truck when I am done. Is por 15 and it's associated materials the real deal. I have all the resporators and all of that, and I do not mind spending the money if it is the best. I would like honest comments.
