Review: High-quality sealant that’s easy to use and delivers professional results - I used STAR BRITE Marine Silicone on my Beneteau sailboat, and it worked perfectly. The application was smooth, and it created a strong, watertight seal that has held up well against the marine environment. It’s flexible yet durable, exactly what you want for boat maintenance. The quality is excellent — no leaks, no peeling, and it looks clean once cured. It’s clear this product is designed with boats in mind, and it gave me confidence knowing my sailboat is properly sealed. Overall, STAR BRITE Marine Silicone is a reliable, high-quality sealant that’s easy to use and delivers professional results. I’ll definitely keep it on hand for future projects on my Beneteau.
Review: Great Product - I used Star Brite products on several projects. On this project, I had a crack in the lid on the recycle bin. This allowed rain to enter and turn paper/cardboard into mush that would not empty. To stop the spread of the crack I drilled two small holes one at each of the crack. I then used the marine grade sealant to fill the crack and the holes. I put a large bead of sealant the length of the crack and spread it out with a putty knife. So far it has worked great. Had a heavy on and off overnight rain and no water inside the bin.
