Gel Coat Labs All Marine Surface Sealant is designed to seal and protect surfaces from marine contamination, industrial fallout, salt air, acid rain and UV rays, making it an essential part of anyone’s boat detailing kit. Boosted by Polycharger® for durable, long-lasting protection, this marine sealant seals and protects painted and non-painted gel coats, stainless steel and aluminum surfaces. Be sure to wash your boat with a quality marine cleaner prior applying marine sealant:

  1. Great product for a quick sealant and and touch ups after weekly boat washes. I use this product alongside other Gel Coat Labs ones and the results are just perfect. This product just keeps the boat clean and shine like crazy! Water beads off as well and it seems to repel a decent amount of boat scum.

  2. This worked wonderfully on my boat and trailer. Use sparingly and follow the instructions for a very deep, high gloss shine. The colors really pop and appear to be long lasting. It works well on a variety of surfaces and is now my go-to surface sealant!

  3. So far so good. I really like the fact that my boat stays clean after it rains. When I do wash it takes very little effort to get it clean, and the shine is second-to-none!

  4. Gel Coat Labs is legit. I’ve used other brands before but wanted to try something different. Reviews and ranking were great so I purchased. I used on my boat as soon as I received it and was blown away with the results. Easy to use and no streaks!
