You have to get it lined up correctly though, as once it's stuck together, it will be really stuck together.......instantly, and pretty much permaneently (as you have to pretty much destroy the cover to get it off the saddle)!

...while I suppose you might be correct, I wonder if you've ever used it for this ? Because it has seemed quite permanent in a number of saddle applications for a number of years, all in use, and all exposed to the sun. It is, as stated, another form of a contact cement, in a spray can, and as such, while it is listed as low strength, in this application it is quite strong enough.
So while I have no doubt that Weldwood and a number of other contact cements will work, I would ask you why you think this one will not ?
I don't want to get into some long exchange here, but if you've used it and it's actually failed in use, it would help me to move on. If not, why state an opinion based on speculation ?
