Vulkem, sikaflex, dicor

Ok I need to get something to fix a leaky window and some roof vent fans. Vulkem is suprisingly not available any where I can find in the metro area which I can not believe. The airstream dealer carries sikaflex and says it works great and that is what the factory uses now. They also have dicor self leveling (thought I might should use that on the roof vents and stuff?). Just wanted to know. If I use Vulkem I will have to continually order it and pay for shipping and probably never have enough when I need it. Sikaflex I can get litterally a block from where I work (that close to the dealer) so I am leaning towards that as to not have to much trouble getting it when I want it. Camping world is down the street as well and they also carry the dicor and sikaflex. Just wondering if Vulkem is worth the shipping hassles.
Being that I am full timing I really don't want to order a case and have to find another cubby hole to stash it in!

Nothing wrong with Sikaflex you want the 221. I use Vulkem because we have cases of it left over from some metal project that specified it. Trempro 635 will work too if you have it readily available, it is one of the newer generations of the polyurethanes. Biggest thing to avoid are the silicones.

Sikaflex is a similar product to the Trempro stuff. They are both polyurathane caulks. You should be fine. I order Trempro 635 from Fastenal.

May be I have to do that in 5 to ten years.
Check out this old post . I would consider this ETERNABOND ROOFSEAL. ALSO HERS IS FINISHED PHOTO.

So I was just at the dealer and talked to the airstream mechanic. He said he uses acry-r. He said yhe sikaflex cracks after a few years from the sun. He said anything out if the sun its great. Anyone heard of this other stuff?

This is also a product that Airstream uses at the factory. They sell it at the factory store and thru the web store. They say it wicks into tight gaps better than vulkem and stay flexible over time without cracking. Ed
