nige Posted August 10, 2004 Share Posted August 10, 2004 Rust Areas & undercoatingThe other rust problem is on the 4-door models, between the rear wheel opening and the bottom rear corner of the back door opening. One solution is to have anti-rust oil compound sprayed inside the back ends of the rocker panels. As per the common problems and fixes thread, my truck ran into the same problem. I should have done this last season, and I was lucky it never went completely through the metal. It would have been a lot less work. Anyhow, here's what to do if your fender looks like this: First, remove the fender flares if applicable. I had to use a grinder on some of the bad stuff. Then begin to sand down the affected area until you get to bare metal. I used a sandblaster and it saves a whack of time. I applied a coat of naval jelly in case there was some residual oxidation anywhere. The area should look like this: If the rust was particularly bad like mine, slap some filler or putty on, let it dry, then sand it smooth like so: After than is finished, you are ready to prime the area. Sand the primer until it is as smooth as possible, finishing on 600-grit. Then apply a fresh coat of paint. I took my truck to my friend's shop to have it done. You can blend in the new paint with a 600-grit wetsand. After that, use a polishing compound and finally apply a fresh coat of wax. This should keep the rust gremlins away for a little while. Has anyone found a paint which has some rubber compound to resist the scratching from the OEM fender flares? I have a feeling that sand between the body and flare is responsible for this problematic area. Link to comment Share on other sites More sharing options...
Mr. Pickles Posted August 10, 2004 Share Posted August 10, 2004 Oooh, fun! I just did some similar to this under the rear doors. I was thinking about sticking on some of the smallest thickness weather stipping I can find between the flares and the body. Maybe that could help, as I'm seeing the rubbing and scratching of the paint you're talking about. I just used the gold color "hammered look" Rustoleum which was close enough since I covered the area with aluminum diamond plate like 88Path did.

nige Posted August 10, 2004 Author Share Posted August 10, 2004 i'm contemplating taking the flares off. THe truck looks a little burlier without them. Maybe put them back on after a lift and those 33" MTR's i constantly dream about Link to comment Share on other sites More sharing options...
jmcardamone Posted August 11, 2004 Share Posted August 11, 2004 How about a Nice coat of GE Top end Clear Bathroom Silicone (a Thin coat). This stuff is Flexiable and resists water dirt and whatnot, and is C L E A R! Repo Depot (home depot) should sell it. it comes in a Tube wit a Clear cap. kinda of a goldish Label. When im done wiht my Fenders, im going to use that behind the flairs. Link to comment Share on other sites More sharing options...
nige Posted August 11, 2004 Author Share Posted August 11, 2004 yeah that might work, i used that stuff to patch up a hole in my boat last year. Although i'm not sure how to spread it out so it looks nice. That stuff is very goopey. Link to comment Share on other sites More sharing options...
