Crossmember Delaminating

It is with great sadness I say my truck has flaws. I mean it is no Horsey rig but not everything is perfect and my OCD is setting in. My truck is very rust free but it seems that my rear crossmember is delaminating. It is weird because the outside and inside are really in good shape but this is still happening. How do I correct this so my truck doesn't turn in to swiss cheese? I have a can of clear waxoil but I was thinking I need some sort of rust converter or sealer first.

Thoughts?

Replaced your rear cross member with a galvanized one

Due to the construction it's just a matter of time. I don't think you can clean it out well enough to even retard it. I think waxoil will just trap whats already in there and it will still rust but from the inside out.

Extreme would be remove the frame and get it acid dipped and galvanized.

Yesssss, I knew it would work! I called Boyd's Detailing Service and the Hermosa Beach Car Wash a few months ago and told them any time an Arles Blue Defender ST went through for detailing, that it should be washed exclusively in salt water.

P.O.R. it Then Waxoyl it, this will prolong the life for a little while, you might have to hit the loose stuff with an angle grinder....

I was out in Vegas at an aviation convention and saw this... they had samples that looked great. They will ship UPS to your house..

www.roval-usa.com

This is the one they recommended for chassis applications

Not sure if it is too late to apply somthing like this..

Sell the rusty POS to me. It's not safe any longer and it's just a matter of time until you have to do a frame swap.

I would think this is fixable, shoot some crap in there and wait ten years

Absolutely
You need to keep those seams open or you will have to replace the parts. Your best bet is one of the better anti corrosion spray coatings like LPS that can get into those crevices.

I wish I had your problem on my truck. I would think POR 15 or Eastwood's rust encapsulator paint in a spray can should slow the inevitable.

It is weird that I have nothing anywhere else. Truck is basically spotless. Well my skid plate turned to dust as well but I replaced that.

when I get seams expanding like that and filling with cornflakes, I take a ball peen or pointed hammer to one side of it and it will break up the crud in the seam. you can blow it out with compressed air. the more layered crud you get out the better because that stuff traps moisture and compounds the problem. also hose out and blow compressed air into the holes in the back of the x-member, get it cleaned out good. then let it dry in the hot california sun. once you have it all cleaned out, hit it with some red primer followed up by a good chassis paint, rustoleum, whatever your poison. you can use compressed air to force the paint further intro the seam. we use that method in the woodshop here to get glue into seams on things we are building so I don't see why it wouldn't work with paint. I could see if the pressure is too high it might blow the paint clear out since paint is thinner than wood glue. once everything is dry and fully cured, hit it with some waxoyl. if you can, get some-a that waxoyl up inside the xmember too.

or, just back up into the tar pits and get a good rustproofing coat the "Horsey Way."

Sounds like a decent plan. So would you hit the bottom of the crossmember with the hammer to break it up? Maybe stick something long and sharp int ehre to break it up a bit?
