Real carnauba wax + protective polymers = shiny, protected gel coat!

Marine 31 Gel Coat Carnauba Wax + Sealant combines the proven benefits of real carnauba wax and advanced crystalline polymers into one easy-to-use formula.  The real carnauba wax imparts a high-gloss, slick finish while the crystalline polymers provide rugged protection against salt and UV rays.  It’s only an added bonus that Marine 31 Gel Coat Carnauba Wax + Sealant is exceptionally easy to apply and remove, by hand or dual-action polisher.

Don’t stop at the gel coat!  Marine 31 Gel Coat Carnauba Wax + Sealant can also be applied to aluminum and stainless steel surfaces.  Regular application will make treated surfaces easier to clean and maintain.

Best there is!
Very good LSP for boats. Some waxes leave the finish a bit flat on gel coat, but not this stuff. It creates a mirror shine (providing all the oxidation is gone and it's been polished to perfection). Love it!!
ProsAmazing shine and good durability.
ConsIt's not cheap!

Well worth the price
I have been a long time collinite user. I would get 2/3 of a season protection out of it in Pennsylvania ( outside wet slipped cruiser).This year I decided to try the marine 31 line of products. Great wax/sealant. Went on easily and lasted the full season. Washed the boat off before putting it away for winter and it still looked great. Won me over.
ProsEasy to use. Long long protection/durability

Easy application
After using the final step polish I applied two coats of this wax and now she looks like a brand new boat. The boat is over ten years old but you'd never know by the shine. I'm very happy with the results.

Best of both wax&sealant
Marine 31 Gel Coat Carnauba Wax + Sealant Is a great choice if you want extreme High-gloss look and extra durability . As supposed to get me up to a seven months of protection will see that :) ... Super easy to apply and wipe off without much of a residue. I prepped the gelcoat with Marine 31 final step Polish.
