One word describes this product..."AMAZING!!" I have a white fiberglass body ranger boat that shows that ugly water scum line terribly. My scum line was thick and caked on the boat due to repeatedly hot weather. I tried everything I could think of. Purchased this product and the water line immediately just vanished after spraying it on. It's like magic!! I am very impressed and highly satisfied with this product!! I highly recommend this product!!

This product is truly amazing. Bought on a whim off the shelf of a local hardware store since the spray application was appealing compared to the paste and rubbing i have done previously. Wow! Amazing results in 20 minutes compared to hours of labor the old way. Took 2 years of Ohio river water stains off a white fiberglass hull in minutes. Love this product.

Spray on rinse off and the scum is gone. Works amazing!!

<p>This cleaner made our boat look like new. Easy to use! I'd give a AAA+ recommendation on this product! Speedy shipping too!!!</p>

Still many don't know that such a product exists
