This stuff worked great!
This stuff works! I knew my boat was going to be sitting in salt water for 30 days, but I was only able to get one coat before launching. I was worried I wasted my time with only one coat, since the product directions says two coats. I would definitely recommend the two coats, but even with one coat, I know it helped minimize barnacles and other growth. I did clean the hull a few times while in the water, and the barnacles wiped right off. After getting home, I did have some barnacle growth, but after scraping them off, I believe this coating allowed the hull cleaner to easily remove the calcium deposits. I will definitely be buying more!

It does what it says … mostly
So it’s pretty good. If you are wet slipping it will mostly keep your boat free of algae. Barnacles it does okay on but not perfect. It is a long process to get it on. 2 coats 4 days. It is a lot of work. Idk if end of day you spend more time then just acid washing your boat end of season. But maybe so. I’d recommend it.

Does not prevent growth
I applied 2 coats on the bottom of a 21ft boat. This wax did not prevent growth at all. I attempted to keep the growth off by cleaning it constantly with a brush but I could not stop it. I had to have the boat pulled, power washed, acid washed and then bottom painted. Do not waste your money on this stuff.

not totally satisfied
After using this product the algae removed easily however, much to my surprise I know have thousands OF TINY BLISTERS ALL BELOW THE Water line. I applied two coats of the product . Anyone have a similar issue. Be Leary of the product. I now have a $3000.00 bill to remove the blisters and apply a epoxy coating and then paint!

Went on easy if left for less than an hour
Used this instead of wax. If I am really impressed (or upset) I will update with season-end results. Went on easy if left for less than an hour. left an application on to "dry" for several hours and was very difficult to wipe off and did not look good. Re-applied and immediately wiped off, left a smooth shine. I am in fresh water with a fiberglass speed boat in a slip for the season, i will certainly test it's claims.

I bought this on a recommendation from a marina member
I bought this on a recommendation from a fellow marina member - I was looking for something akin to bottom paint. Didn't want to bottom paint my older, trailer-able boat that was going to be a dock queen for the season in Great Lakes fresh water. Skeptical, I followed the directions and put two coats of this stuff on the hull, going about 6" above the normal water line. If you're concerned about the price and coverage of this product, I had about a third of a bottle left after two generous coats on my 24' Sea Ray. She went in the water on Memorial Day weekend and didn't come out until well after Labor Day weekend. It did not come out for a hull-clean once, although I did have the best of intentions. Aside from the zebra mussels on the lower unit, the algae-beard that grew all season on my boat hull did come off rather easily with a power washer and a good scrubbing with hull cleaner. It appears that the wax is still on there after cleaning, as you see the thin translucent film it leaves behind. I do plan to use it again next year.

Super Slick.
Goes on as directed. I bought this to protect the bottom of my boat while in a slip this summer. So far seems to be doing the job. I'll let you know at the end of summer when I take it out how easy it is to clean off river build up.

Great
Really helped my boat stay free of green stuff. Towards the end of the season it built up more, but came off extremely easy. I will be using every year from now on.
