I have been redoing a 30k mile 2000 Dodge Ram 4x4 deisel dually that was bought new. It is a work truck and is used to pull when needed. This is not a show job but is being done as a no holds barred job that hopefully will last longer then the factory and prove to be better then the crap POR-15. I knew POR-15 was crap when I put it on but figured it had to be at least better then nothing. I think you will see it was probably better left alone then putting this crap on.
