<p>Works great! Spray on - hose off. I keep my boat in a dry-stack facility, so it doesn't get bad stains anyway - but the best prize was that I don't need rubbing compound to get the shine back on the Merc. outdrive. Again - spray on - hose off - shiny black is back!</p>

Cleans fiberglass quite well. My only complaint is that it leaves an oily residue behind.

Overall, happy with the product. First time I have had to buy a product like this.

Great stuff. Easy to use. Leaves a great sheen. After using it last summer on our houseboat, this was the first time we didn't have mildew under the duck bills in the spring when we returned after the winter. This year I also used the sealer.....this boat glistens!

The performance of the product meant my needs for the boat. Was it a lot of work spraying and brushing, yes, however, after three times, most if not all the algae came off.
