Does your boat have leaking windows? We’ve discovered a wonderful product for leaking boat windows. This is something a power cabin cruiser and sailor alike will appreciate knowing about.

My sailboat is a 1985 Newport 30 and while she’s a great boat, she’s starting to show her age. During this winter we discovered three of the windows were leaking. After a bit of studding we discovered that the water was coming in between the glass and the seal. We tried some silicone to seal up the outside edge but it didn’t work. We scratched our heads and frowned at the windows. As everyone knows, the Pacific Northwest is green because it rains forever here. The running joke is… “People don’t tan here, they rust.”

I sat pan under the leaking windows to catch the drips so the cushions didn’t get ruined as the winter rains fell. We tried several times to caulk the leaks but nothing seemed to help. We started to think we’d need to replace the windows, an expensive project that we didn’t relish.

My hubby discovered a wonderful product. Captain Tolley’s Creeping Crack Cure. This product is a co-polymer sealer that is so thin it can find its way inside fine cracks by capillary action and then dries to a flexible clear seal. It’s easy to use and best of all it’s inexpensive!

We’ve applied several thin applications to each leaking window and so far the spring rains have stayed outside. No runs, no drips and best of all; no errors.

It comes in a plastic bottle with a nozzle top and looks kind of like watery Elmer’s Glue. Make sure your window is clean and dry. Then apply a sparing amount of the product at 30-minute intervals until the crack is filled. You’ll know it’s filled when the product doesn’t disappear. Wipe up any excess and let it dry. So far we’re really pleased with this product.

It works on wood, rubber, glass, metals, Perspex, some ridge plastics, fiberglass, ceramics, concrete, brickwork and old sealants. Will not dissolve polystyrene.  So the next time you need to fix your leaking boat window remember this product.

Hi Edgar,

Please forgive my lateness in answering but my life took a turn for the surreal. Things are only just beginning to feel normal again.

You can find this at West Marine and probably most such places.
