Well, I actually do clean,wax,shine what ever needs to be done, under my trucks. Hey,I like to keep them clean, and yes my neighbors might think I am nuts, but I really don't care. They are the same people that take there cars in for oil changes, washings, detailing, and repairs. That doesn't bother me, I just set a kick out of doing it myself. And yes that polished stainless steel system on both my truck looks sweet, and I'll be keeping it that way. Oh, yes I clean the engines, transmissions, paint and clean there drive shafts too.
