Rust Prevention

Personally I want that shit to leak everywhere and get in every crack & crevice. If not, by the time you discover rust from the inside, it's too late. Small inconvenience for a few days of leaking.

But, what your doing is muuuuuuuuuuuch better than not!

 

There's a fine line between creeping into cracks and crevasse and and not lasting for a long enough time.

 

Right, the body cavity wax also flows cause it goes on as a liquid but after it dries you can actually work on the underside of the truck, I spray it every fall and it looks great.

 

It's quite expensive $1200 and they need your vehicle for 3 days. I think I am going to go through with it since they do so much and I plan on keeping the truck forever and then fluid film certain areas still for overkill. The cosmoline link I posted details the actual stuff and does say that it still stays slightly flexible.
