Looking for advice on what to do about rust. Hopefully the pictures show up in here. I dont think the rust is too terrible, but if I keep this thing long term, I'm thinking of going the POR15 route soon. So far nothing has broken except for the brackets that hold on the running boards (just one). I'm worried about the front piece thats under the radiator. The rust is also all over the connecting pieces I believe that are either lines for fuel or brake lines.

Any thoughts? Thanks!

I thought POR15 was the answer, but I am not happy with it. I found even if you follow the directions you have to remove every spec of rust or it comes back. I scraped and wire brushed everything so there was no loose rust anywhere and then did the prep work and application. One year later rust was popping the POR loose and coming back. I spent 3 days on it and was not happy with the results. I think it would be a great product on new bare metal as a sprayed on base coat. Now i wire brush any loose stuff and spray fluid film on the underside. I did it last fall and although it is washed/worn off now I think it kept the rust at bay. It should be applied 1-2 times per year. No biggie as it is easy.
 
This works really well at getting down to bare metal compared to wire brush

So, i'm in the same boat as the OP, except the dealer I bought my runner from rattle can undercoated over the rust and it wasn't noticed right away when I bought it.. will that actually work with the rubberized undercoating? I bought some of the Mar-Hyde 1 step rust killer and went to work with a grinder wheel and brush cleaning the frame, but that gets gummed up way to quickly.

I don't have any experience removing undercoating with it...it would be worth a try though.
 
Damn, looked at your pics. THAT is some rust. not the worst ever, but....

So, I've looked into cleaning up my frame, and started the process. No where near what you've got going on. but heres some info.

Ive found the reviews exceptional for the VHT rust convertor. Its a start

wire wheels, flap disks and an angle grinder are your friend. clean it up- lots of elbow grease :(
