Totally sealed! Drys clear, easy to apply, good value for money, no mess. Review: Good for small jobs - This product is only ever going to seal the smallest of leaks or cracks, being in liquid form as it comes out of the can, drying to a plasticky finish. But in these cases it seems to be quite effective, if layered as suggested. You need to spray thinly, leave for 15 minutes and then do several times more to build an effective covering. If you're using inside I'd advice the use of a face mask. It has a strong aroma and being an aerosol does fill the air, which is not only bad for the lungs but has a strong pear drop aroma. But overall, if your gap fills the criteria it works well, though I have no idea how long it will last. ## Features - Causes serious eye irritation. - Causes skin irritation. - Contains sensitizing substances.
