Well I went a little crazy with the undercoat when I got my truck getting two seperate applications at two separte places. After putting a tractor muffler on the old girl, I noticed that some of my frame plugs were there and some wern't. To my surprize it is pretty dry (no oil) and full of debris, a little rust mosty dirt (could be from me, LOL) My question is are those frame plugs even good to have on? I blew most of the debris out with the power washer, now I just wanna fill my frame with oil. Think I will just go buy a couple cans of rust check and put them in there. Maybe I will go back to krown for a reapplication!@
