Hey guys, I've decided to get my hinges rhino lined. I made the decision to do this instead of just spraying them myself because the Jeeps only a year old and the hinges have taken a shit kicking all ready. I figure the rhino iiner is pretty tough so I'll pull the hinges and drop em off to be sprayed in the next couple of weeks.

My question to you is, should I have the back side of the hinges sprayed? I've heard a lot of people who've done this say that they've put something on the back of the hinge before reinstalling as the hinge and body are different alloys. I figure if I just get the whole hinge sprayed it should take care of this issue?

Thoughts?

 

Really? No one?

 

There's a thread running in the Stock JK section at the moment discussing hinge corrosion/oxidisation, & the common consensus seemed to be that the problem was caused by the aluminum hinge sitting directly on to the galvanized steel door skin causing metal-to-metal contact.

The suggestion to those repainting the hinge was to make sure they painted or bedlined the back of the hinge that would be touching the door in order to stop this oxisization (resulting in paint peeling/bubbling on the outer hinge surface) caused by the reaction of the dissimilar metals to each other.

I know that when I'm working on Aluminum boats I always use a rubber/silicone washer when using galvinised, brass or stainless steel bolts & fittings to avoid metal-to-metal contact for this very reason (the reaction tends to be accellerated due to the salt water).

 

I did the back

 

Thanks for the input.

 

Just make sure when you drop them off tell them to coat the back less then the front a little bit some of those guys can be quite generous with the spray. Last thing you want is scraping it off cause it wont line up right.
