i've been disappointe by silicon thinking of it as a glue. When I've used it for sealing things, after a while the bead separated from the sufaces allowing water/moisture in. I noticed that all the caulking around around the metal trim on my garage has separated. I can pull the caulking out in one solid piece. A contractor installed the siding, the trim and what looks to me like silicon caulk.
couldn't tell you how long or if it depends on being outside in the cold or sun..
the guy at the hardware store said there are different types of silicon and the more sticky the more expensive. I couldn't tell which are/aren't sticky. hence why i use shoe goo for water tight seals and even glueing rubbery plastics.

The guy probably used interior silicone calk. Which will not stretch in weather conditions. I have used exterior Latex calk with silicone on an awning, around My garage, some window trim and many other outside projects, that were done many yrs. ago, about the mid-80's. I have lived in the same house for 39 yrs. and not any of those projects show any signs of what You describe. The calk I used was not cheap, even for the 80's. I even used it on My 27ft, cabin crusier that I used to have, was waterproof, along with fuel proof. Contractors today are a dime a dozen..................
Take Care!

All of this talk about caulk reminded me of a window sealant that I had used years ago during the winter to seal out drafts. The sealant was easily removable in the Spring when it became desirable to open the windows for fresh air.
I did a search and found DAP SEAL 'N PEEL Removable Weatherstrip Sealant. This could well be the answer to what I am looking for.

Anyone have any experience with this product?

Hi Rich,I’ve used this for the same reason you did. It worked well for the winter then peeled ot off and discarded in the spring. Only concern I would have is how long is it good for? Will it dry up and crack in 5 years? A call to DAP will probably answer the question.

This is the stuff I use to seal the gromets on plastic out-buildings, such as garden sheds, and to seal around the down-spout drains on my eave gutters. (Commercial link, but no affiliation, just a handy site on first search for PARR):

This stuff is easy to use, and it dries semi-clear to a rubbery and durable finish.
