Vulkem has been replaced by?

[KyMoonshine]

Hello
Last time I was at the mothership for repairs I bought some tubes of sealant in the Airstream store and they worked incredibly well on a bunch of projects I have had since then...But I can not remember what it was called...I think Airstream used to use and sell Vulkem but I recall it being replaced by something else now...I looked in the online Airstream store and they sell a few things now...I need to seal a leaking skylight and was wondering what would work best? the stuff I purchased at Airstream flowed out of the gun smooth and self leveled into a wonderful flexible seal...kinda like magic..lol...I see they sell Sikaflex-221, Bostik 1100 and Adseal Adhesive Sealant..I guess I could order one of each...what are you guys using? Thanks

Also searching around here on the forum I see something called Trempro 635

I think Trempro -626 is the old Vulkem. Most of use use Trempro-635. I think Airstream uses the Silkaflex 221 now.

The specs of the Trempro-635 are better.

Thanks everyone..I just notices Vintage Trailer Supply sells the Trempro and I like dealing with them so I will give it a try..

A lot of the time they are out of stuff like Trempro.

Fastenal has it...mostly in stock. Available within a day if they have to order. They sell rivets too....no Olympics though.

Does anyone have experience with 3M or Loctite polyurethane sealant? I live in a rural area and some of the products that have been mentioned here are not available locally.

I don't mind ordering if I must. Just a lot more convenient to pick it up here.
