Old thread resurrected

I purchased these two sealants from Fastenal a few weeks back. Has anyone ever used the 3M 560 polyurethane adhesive sealant? It was a bit expensive at $15 per tube. The Tempro 626 is supposed to be like Vulkem 116 but has less work time. I have been using the Sikaflex 221. It has a nice finish to it. I don't dig the texture of vulkem.

I've used Sikaflex 221 and Trempro 626 both having good results. No clue about the 3M PU stuff though. I like the Sikaflex because it is really thick, and can be sanded down (I'm talking interior use for that).

We have a '70 Overlander. We just pulled the musty carpets and found 2 layers of the bad boys. We also pulled the gaucho and table. Here are some pictures of the floor. Suggestions of what caused these leaks? Rivets are intact outside the leaks, the striping along the edge looks a bit worn, could be a source. Suggestions?

Vulkem is now called TremPro.

I used TremPro 635 in white for caulking around the Fan-Tastic Fans on our Safari last fall. (TremPro 636 is available in aluminum color.)

I mentioned this in SilverGate's Safari is Home at Last! thread, post #484.

See details of this story in Fall Safari Prep, History Safari Express.

Start at the top and work your way down. The vents (sewer and air) and AC were both leaking in our 73 Tradewind along with the windows. We havn't had a blowing rain since the constructor dug out the old vulkem and reapplied new. I think it is on page 1 of this thread were Andy describes sealing things. We have also installed all new window gaskets.

Having now applied both, I prefer Sika 221 because it is smooth. As far as how they stand up over time, I'm not sure yet. There is a good read on sealants under field notes on the VTS website.

Sikoflex is smooth and dries fast. Do not use it when doing sheetmetal work

Vulkem is course and dries slow.

They both last a long...........................long time.

Sikaflex

Talked to sikaflex rep today he recommended to me 295 Marine Grade with activator because it wont chalk and has better uv stabilizers,sooooo at 11 bucks a tube I am using it on the stacked windows (only comes in black and white) I am using black and man is this stuff thick and nasty. Thanks Top,Constructor and of course Andy. I was reading that for the sheetmetal seams to use parabond but someone else mentioned another product Dymonic then theres dicor lap sealant?? Whats your take on the skins I am thinking Dymonic or Dicor. OHHHH Dont get any kind of alcohol on silka until it is cured completely or it will fail prematurely, straight from the rep. I had read where someone was wiping thier seams after applying sealant and using alcohol.

I am a big fan of SikaFlex in all of the flavors. Works great in all recommended uses. I would not use Dicor lap seal though, as I have found that it tends to dry out after a couple of years of exposure to the elements and starts to exhibit shrinkage cracks, especially when used on roof sealing applications.

I have always been partial to 3M products. I found this spec sheet on their website.
Looks like some good products to try.
