i have used this stuff for a multitude of uses, from "gluing" [?] on those plastic window shields [that allow you to open the window a crack when it's raining] to sealing up the drain plugs in the back yard decorative fountain.
the "adhesive" stuff works way better than the stuff labeled "clear silicon".
and yes, surface preparation is paramount to any use of material such as this.
the stuff i had been using was an "off brand" [made by Dow chemical for industrial use] and was in what i call a "cheeze whizz" container, one that you push sideways to make the stuff come out of the tube.
as i had previously used the google to try to find more, for some reason, all that would come up was just "clear silicone" or "clear silicone sealant", with out the "adhesive" on the container.
thus my quest here to see what was being used by you fellows, with the emphasis being on "adhesive".
