Seams sealant bleeding.

I have a 2004 classic 31 ft. It seems that the sealant is weeping out from the seams. It looks like hair blowing in the wind while riding a motorcycle. Is it epoxy? If so I read that a heat gun will help remove it. Cleaning fluids are not working. If I scrape then I mar the skin. What caused it is a mystery.

Never heard of that happening before on an Airstream product. Sounds like whoever owned it before you used the wrong sealer on that trailer. Can you contact the previous owner?

Filiform corrosion is the aluminum corroding under the clearcoat. It happens when water gets under the clearcoat, usually near the edge of a panel.

Lots of threads on this. Search for filiform.

I have noticed that it is only happening on the side that is not getting sun. My trailer is under a cover and the sun hits it on the side facing the noon sun. In some places the clear coat is coming off like powder. Amazing. Something else for me to do.

Naw, just get some crappy eyeglasses next time. What you can't see won't bother you.

Not when it eats into the aluminum. Thanks for the Texas wit. Living in SA I understand Texas humor.

It's cosmetic. Looks bad but will not eat out the aluminum.

Texas humor does have it moments. I recently had a truck with an air ride seat that had no give. A 260-lb friend jumped aboard to test it and declared it was about as effective in its job as throwing a saddle over a cinder block.

If you live in Texas then I have two strong recommendations. One, a full size dehumidifier (80-100 pint); two, a full cover under which to park to keep sun, polluted rain, hail and the rest off. An enclosed structure is really best. Second to a garage is one which keeps afternoon sun off, not just overhead.

Trailers sit a great deal, and the elements really work on them in this state. My Dads changed quite a lot in appearance the 27-years he had it.

Ive read some of the filiform threads and recommend them. As mine has an anodized skin, it's a different set of problems. Add in possible skin replacement and it's worse (easier to get an AS panel redone).

Good luck

Average humidity in South Texas today is over 70 percent. I run a dehumidifier full time. It has probably saved my bacon on several occasions after having discovered a wet carpet in the bedroom. I think it's money well spent. Right now pulling up the flooring and it's running like gang busters.
