    • Excellent Shine and Protection – Great Marine Wax
Size: 128 Fl Oz (Pack of 1)
Review Image by Yunia
I’ve been using this marine wax on my boat and I’m very impressed with the results. It gives the surface a deep, clean shine that really makes it look well-maintained and polished. The application process was simple and didn’t take much effort. It spreads easily and buffs out nicely without leaving streaks or residue. What I like most is the protection it provides. It helps repel water and protects the surface from sun exposure and salt, which is very important in marine environments. Overall, this is a high-quality wax that delivers both shine and protection. I would definitely recommend it to anyone looking to keep their boat or marine surfaces in great condition. ... show more

    • Very happy with my results from this product!
Size: 32 Fl Oz (Pack of 1)
Review Image by Kathleen Bliss
This stuff worked like magic on an old duracraft boat we just got . The paint was faded and chalky and looks rough. It was easy to apply using some waxing pads and applied according to the directions. It made the oxidized paint look great again! A little goes a long way too!

    • VERY GOOD WAX, BUT HARD TO REMOVE BY HAND
Size: 32 Fl Oz (Pack of 1)
I read many of the reviews here about using this on cars so I wanted to give it a shot. I have a jet black corvette convertible (C-5). I would give this wax 5 stars but for the difficultly of removing the wax by hand. It is liquid and goes on quick and easy. I put it on my cool car (84 degrees but high humidity) in the garage. I waited about 15 minutes then tried to remove the dried wax with a cotton terry cloth towel. It left horrible swirls and discoloration on the car. It actually freaked me out. I moved the car into the sun for 10 minutes then went out with a clean microfiber and just rubbed and rubbed.... The end result was fantastic. The car is as slippery as ice and has a deep shine. However, if you are going to use this wax you should probably have an electric buffer. ... show more

    • Great Marine Wax!

I’m that guy who keeps their stuff clean. I do a complete wax job on my 2012 Everglades 243 about 3 times a year to keep oxidation to a minimum. Zoom in on the picture. Since 2013, this wax is all I’ve used. This wax combined with Meguiar’s marine ultimate compound and cleaner (blue bottle) and their marine quick detailer is all you need. I’ve done with machine and by hand, either way works, pretty easy on and off. Wax it in shade or early morning (not full sun) for best results. Tight Lines! ... show more

    • My go to marine wax every season
Size: 32 Fl Oz (Pack of 1)
Nothing I have tried beats this for keeping my boat looking clean and protected. It goes on really smoothly and does not haze up or get hard to buff off like some paste waxes. Water sheets right off the hull after application and the shine holds up for a solid chunk of the season.
