Ron - yeah, I was thinking about that tonight on the fill up/test drive and after reading Rovers/Phillip post this afternoon. What do you recommend for getting inside the frame? Obviously I can't prep it save for blowing out any dirt w/ the air hose. A quick search on Rovers North seemed like this might work - http://www.roversnorth.com/store/p-5...l-aerosol.aspx
While the bumper is out, the rear crossmember will be reconditioned. I'm starting a search for how to do it on the outside but agree with spraying something inside the knooks. I really couldn't believe how much dirt had accumilated after I took the tank off. And I had steam cleaned/air blown the underside really well after the last 4 wheeling trip. My thought now is to get the rear bumper/cross member done and get at each corner one at a time on the warmer spells during the winter months in the garage.
Sucks that I should have just done the inner part while the tank was out and the truck was on ramps but didn't know how bad it was going to be. At least with my truck there wasn't much rust just the amount of dirt - which can hold mositure and will be rust in the future.
