What did you do about interior frame rust?
 
Found a healthy amount of chips and such in my frame. PO painted the frame or something, so it looks great on the outside. No spots where I can put my finger through or that even seem weak on the outside. Just not sure what to do about the inside?

Unfortunately by design the TJ frame rots from the inside out. Short of keeping the rust chips, sand, salt out of it there's not too much you can do.

Easton internal frame coat. Get two cans and watch the video how to do it. I love the stuff and recommends it for all jeepers.

I have heard of hot oil and wax treatment but do not know it personally .

I meant Eastwood Internal Frame Coat. It's basically a can of rust converting spray paint with a diffuser on the end of a plastic tube so that it coats the frame interior. I will be spraying it on my next jeep and it's on the one I have now.

Did you get the chips/debris out of the frame somehow?

I heard fluid film is supposed to be some good stuff I'm planning on upswing it in the inside of my frame because it creeps so don't have to worry about being perfect and coating it perfectly.

The question still remains as to what to do about the rust chips inside my frame, drilling a hole and attempting to get the rust out is the best I can think of - but where should I drill the hole?

I am in the same boat. I am going to drill a hole right before the bend to go up over the axle on both sides. There is tons of crap in there that needs to go bye bye.

Maybe an air gun will blow out some or the chips. Make sure it's all dry in the frame and coat the dog piss out of it. Metal is always rusting but it rusts less when dry. So if it's dry and you cover it with some type of protection it should last a lifetime or so.

Thinking that's the best way... Any idea of how big you're going to drill the hole to be?

I just coated the inside of my frame with Eastwood frame coating. To clean out the junk in the frame I used compressed air in one of the holes in the front and a vacuum in one of the large hole in the rear. Worked good.

Yes X3. First I used a magnet on a flexible rod. Just continued to work the magnet as far into the frame as I could. Got piles of junk out. Then I started the compressed air/ shop vac routine. Place the shop vac hose downstream in the frame and blow from above. Takes a while, but I got tons of crap out. The Eastwood product is awesome. I actually used 4 cans, 2 per side. Make sure you put down Kraft paper or many rags. I coated mine up real good. It was dripping a bit here and there. The nozzle on the Eastwood product works really well. Has a 360 degree spray head on it.

I just ordered 4 cans for our 99. I drilled drain holes in the bottom of the frame the other night. Amazing what ran out of it.

Have to do this soon as well.

Where'd you drill the holes? I'm thinking about doing this and was contemplating welding some 1/4" to the frame first before drilling... Overkill?

Bet 05-09-2013 07:29 PM

I think drilling the hole before the frame goes up over the rear axel would be the best spot. 2 cans of the coating enough?

obiefox 05-09-2013 10:31 PM

I drill holes front and rear where the control arm mounts are on the frame. This will let the mud and water out. Once clean, I spray the inside of the frame heavily with fluid film. The eastwood stuff may be better if you already have extensive rust, but I think the fluid film is a better preventative.
