I just picked up a 2003 in good shape. What have you done to keep your nice frame nice?

in addition to the drain holes mentioned above, I've been spraying mine with boiled linseed oil cut with a little water. someone posted that recommendation on this forum some time back and it seems to be doing the trick.

I just heard recently that dealers are voiding warranties because FF is being found to accelerate deterioration of rubber bushings.
I've been recommended this by my welding guy
https://www.berkebileoil.com/protection-first-class.html

I've been using Fluid Film on my son's Jeep for over 10 years and haven't found an issue with any rubber bushings. It sucks to work on at times because it is greasy and dirty but no signs of rubber deteriorating. We do it just around Thanksgiving time each year. Up until last year, he used it as his daily driver up here in the NE and the frame and tub are very clear from rust.

Edit: Per FF website FAQs: FLUID FILM has no adverse effects on plastics. Caution should be used around non oil-resistant rubber goods. May cause swelling.

The use of "May cause swelling" in their FAQs is probably the prompt the dealers will use to avoid warranties. Don't get me started on dealer warranties these days but thats another story. However, I don't think any of our TJs are under warranty any longer.

I like Eastwood's internal frame coating, I've used it on a few vehicles, and it seems to be holding up, but it can be messy to apply.

If anyone is semi-local to me in the People's Republic of Maryland and interested in this product, I've got (7) new cans of the green Eastwood internal coating up for grabs. If it weren't for the hazmat crap, I'd ship 'em.

Actually, suppose I could ship, but not sure if it would be cost-effective (I have no idea what the upcharge is for shipping explosive aerosols).

Thanks all, I know it's a topic that has been beaten to death. Just figured there .ight e new tactics in 2024 :) just hate to drill holes in an intact frame. Figured no could force feed it some fluids down the frame rail ever couple months, or long hose and some POR in the trouble areas

What I was told is that it gets drawn in between rubber and metal, pulling dirt in with it and the movement of the dirt "sands out" the rubber. True? I don't know, but something to consider
 
I’ve used the Eastwood internal frame coating in black and it’s holding up well.

Likewise-done in late '19 and it's holding up perfectly. I also use cosmoline on exposed surfaces underneath. It's entirely annoying to work on coated parts, certainly, but I will take that over rust every time.

The frame holes you drill behind the front CA bracket and in front of the rear CA bracket ate to give a place for water to drain. Those are the two low spots and where water tends to pool.
