When I picked up the trailer from service a few days ago the guys gave me an opened tube of CR Laurence Polurethane (CRL). it looks like Vulkem but is a little eaiser to work with. Its this stuff available retail.

Thanks

Try SikaFlex 221 polyurethane sealant. It's what the Airstream factory uses and the only sealant that I use...........very smooth and BOMBPROOF. Just don't exect to remove anything you seal with it without a lot of cutting and effort!!!!!!!!!!!

I fully agree! It skins over much faster than Vulkem -- within a couple hours or overnight for sure. The gray is an excellent match for aluminum. It is pretty easy to obtain over the internet from Austin Hardware - Austin Hardware & Supply Inc. :: Sealants & Adhesives :: SIKAFLEX 221 :: 221-G (thanks to Markdoane for this source). It isn't available at vintagetrailersupply.com.

Thanks for the info about Sikaflex. It sounds like a wonderful product!
I am having a problem removing clear silicon (about 6 foot) installed over a seam by the PO. With the help of a razor blade, I have very carefully removed all but the last layer of silicon. The adhesive remover (by Ace Hardware) and everything else that I have been told to try, has failed. Any ideas? I know the silicon will melt under heat, but, no torches please!

I have found that Mineral Spirits work well on silicon. At least it help me remove the glass from the frame that the PO had used to help seal them.

OUCH! The last time I bought Sikaflex from Austin, it cost about 1/4 the current price. At first I thought they were pricing it by the case.

Robert,
Thanks for the mineral spirits tip....have tried and it seems to dissolve minute pieces of the silicone. Maybe I have to just keep rubbing eehh? We all want a miracle cure! Thanks again for the info, and have a great day. I am back to the silicone beast.
