Davis Fiberglass Stain Remover (FSR) is a unique stain absorbing gel that serves a variety of purposes. It is ideal for removing oil, rust, exhaust, waterline and transom stains. This product also works great on shower stalls and furniture made of fiberglass.
Its non-abrasive quality means that it is safe to use on white painted surfaces as well as on gel-coat. Just don't forget to test a small area to be sure FSR will not damage the finish. This product requires no sanding or compounding, and can simply be applied with a brush, sponge or cloth. Wait a few minutes and then wipe or rinse off.

Bought this to try on the iron stains in the bathtub and sink in the house. It is great! Easy, no fumes, worked on fiberglass, porcelain, chrome. Seems like it takes longer for the staining to come back. Had my wife hold off on her normal cleaning routine to let it get worse than usual. Photo is the test results.

I use this for cleaning the waterline on my boat. We boat in a river that has a lot of tannins in the water. A week in the water and we start to see brown staining. I put this on a sponge full strength and apply it to the stains. By the time I go all the way around and come back to rinse the stain is gone. It's bottom paint safe so if some of it gets on the paint it doesn't stain it which some products do. I was using this last year on the beach and the guy in the boat next to me was watching as I went around. He came over when I was done and was amazed at what I did. It took me about 5 minutes to go all the way around and clean all the stains off the boat. He said he's looked for years for a product that did that. I walked over and did his boat which hadn't been done all summer. Took it from brown to white in about ten minutes. I could have sold him my bottle right there if I wasn't so attached to it! One large bottle "big job" lasts me just about two seasons. I use a little bit every weekend.

I had deisel oil stains on my sailboat. Nothing I tried would even partly work. This stuff was amazing. Brush it on, wait a minute or two, and wipe it off. Awesomw. And no effect on the color od the boat (white).

This product does NO MORE than any stain removal product. Davis FSR states that it will remove bathtub rings. Duh. Big deal. I PAID OVER $30 TO GET THIS"MIRACLE" PRODUCT??? It did nothing to remove the stain on my fiberglass tub! We had a 8X10 pad on the tub that left a light brownish stain on the tub & pad. I think it was algae, not sure though. My wife researched "stains". I went thru numerous methods; Davis FSR being the last resort. This product does not do any more than a $3 product.

This stuff really works. Took a neglected boat and made it look like new! Nothing else has ever come close to working this well, and I've tried them all.
