I just purchased my 1st Jeep (2010 Wrangler Unlimited Mountain) and every used JK I've seen, first point of rusting, is the door hinges. I have, and heard, several good explanations why, however I have yet to come up with, or hear a good idea how to prevent this seemingly inevitable issue. Any good ideas out there?
I was looking for the "easy way," hope somebody has one.. I didn't even know about the problem 'til I went in the garage and saw the streaks after washing (and drying it the night before) NO problem locating the problem, when you bought dark green...
I work for a Jeep Dealership Body Shop...We've done a couple repaints so far, mostly older JK's though (07-08). I just bought a 2010 beginning of June 2010. I am hoping I don't have to repaint hinges. One of my Painters has a 08 JK too. LOL
My wife's Jeep had the Tricare anti-rust module installed when we bought it, and it doesn't have any new rust on it since we bought it (it's an '06). My Blazer (without the rust module) rusted all over the driveway!
When I bought the Wrangler, I knew about some models that had hinges rusting (I saw one with bubbling at the dealership), so I immediately went with the module on this one too!
POR 15 is incredible, I used it on my trailer last year and it survived a salty winter and not a hint of the rust re-emerging. The MOST important thing is the metal prep; follow the instructions to the letter and make certain the surface is completely free of grease, goo and flaking rust. Poor prep = Waste of $$$$.
I just brought my 2008 Wrangler unlimited to the dealer. I found rust bubbles on 3 out of the 4 front door hinges. So far no signs of corrosion on the two back doors. The bad news is that my dealer told me that both front doors show rust on the door body when they unscrewed the hinges. I'm afraid whatever they will offer as a solution it might come back as a problem in future. On rainy days and after washing my vehicle water poor down from the mirrors just on the front door hinges. The different materials of doors and hinges seem to work as a chemical element provoking the corrosion process. What about a plastic layer between the door and the hinges? Any help warmly welcome!!!
My new to me 07 is immaculate, well-except for the hinges. PO touched them up. not really noticeable unless you look, but my jeep is black so.
You figure jeep would have this figured out. I never understood why they rust
Fluid-Film (Fluid Film® | Corrosion Preventative, Lubricant and Rust Inhibitor), every 6 months. $15 per aerosol can that will last 10 years if you use it only for the hinges. Also works great to prevent frame / undercarriage rust - just spray generous amount before each winter season. Two cans will suffice to get the whole car done. Repeat every year and you'll cut rusting by 90%.
