Leaks in the decorative molding!

I searched and didn't find anyone with this problem. frank spent some of the rainy day inside the airstream, and now it appears that the decorative stripe (some AS have blue, ours is wood grain) halfway up the exterior is leaking at the rivets. Has anyone seen this before??? We have visions of lots of silicone remover, and Vulkem in a syringe again. Argh!!!

I'm not sure Silicone is the right stuff to use....I think Airstream uses Silkiflex (sp?) in all areas except the wheel wells. I seem to recall a number of posts saying stay away from silicone.

She's talking about removing silicone, not using it.

Sharon, could the moisture be from condensation? Or is the moisture in one specific location?

Are you talking about leaking into rivet holes at the beltline trim strip? About the only way to see this would be to have the inner skin & all insulation out. Or else I'm not understanding at all. Could you provide more information please? Thank you

Yes Bob, good questions! The skins are out, the smelly insulation is gone, and frank has watched the water come in through the rivets. Do we remove the plastic strip and reseal the rivets on the outside, or remove the already plentiful silicone on the top edge of where the body meets the molding and replace it with Vulkem?

Yes remove the silicon, but to put a bead of vulkem on top is not the best idea, water can get in there from the bottom with road spray and condensation.

To fix it 100% you need to remove the belt molding drill out the rivets and replace with new rivets and vulkem.

Another quick fix that would work is to cover each leaking rivet with a dab of vulkum from the inside?

I think the concern with sealing the rivets from the inside would be that the water can still get between the molding and the outside - we're worried about any amount of freeze/thaw expansion here in the Great White North!

yes, but that risk would be true even if you never had a leak as of now.

If you clean out the mating surface of the molding with something like a credit card and wash it out good I think that may help water from being trapped.

The vulkem will stay plyable a long time, if it didn't work over time you can then remove and re-rivet it.
