Wanting some opinions here on the rusty door problem our rams have. I'm about to drop $1000 on Omni plus paint to put a new paint job on my truck. I have a great body man who is helping me do it right. I'm doing all the grunt work. 

So my question is what would you do to repair knowing you are trying to put a quality paint job on. 

Good question. I dumped oil in the doors and packed grease in the folded lip and the rust hasn't grown. How to fix it? No clue. 

I have three options. 

A 2" patch for each door skin. Patches will have to be butt welded in and the. Bondo sand prime and paint. A lot of work but lowest cost option. 

I could buy whole door skin from lmc, and remove old skin and attach New to existing doors. That costs a lot more but would be easier to install with less welding and no butt welds.

Or I could buy used (no rust) doors and prime and paint. Way expensive but no welding and I'd have to find them of course. 

In my opinion you can't stop rust, cut it out or replace whole door. Changing skin and not inside part will make it come back, you could send blast inside part before putting new skin on. 

I think sometimes it's cheaper to get a rust free gasser with bad motor or tranny for cheap. 

I also sprayed oil everywhere I could in my truck, it seemed to stop the rust or slowed it down tremendously. Just park it on gravel somewhere overnight. And don't use used oil. My doors were worse than yours. If your doors are that way, then alot of other places will be same. 

One thing is for sure, if I do this, I want to do it once. After this new paint job, I don't want to see the paint bleed red!!!!

My doors look about the same a yours. A 15 year old truck is gonna have some issues. I think mine is worth a paint job but cant disagree with what @Dieselfuturesays.
