I've heard some people pour in cans of oil in the tail gate area to stop further corrosion and rust from forming or "destroying" What happens later if down the road that I want to paint my truck or do some body work on the panels or wheel wells then WHAT? And what about the smell and the drippings---what if the oil drops catch fire on the exhaust system? What is the best advice here...I need some rust prevention in a big/CHEAP way... and I'll be willing to try anything once, more if I like the results! Anyone heard of this before? I live in Maine--we salt the roads here cause there are lazy ass snowplow truck crews that would rather not come back and plow the area they just had been at.., -Dv8 "You tried your best and you failed miserably.The lesson is, never try"
