Ive alwasy been a skeptical person when it comes to consumer products, and this time was no different.
I was always taught, "the harder you work, the better results you get" and this time was different.
The harderst part of this whole deal, was getting in my car and driving to west marine to buy it.
It was a simple brush on and wash off process.
I didnt really think that it would get off all the horrible yellow spots that were on the hull, but IT DID and Im a happy person about that.
Looks like new again. Will highly recommend.

I clean my SeaRay's hull each year, and after reading a positive review in a boating mag, I thought I'd give myself a "treat" with this easy-to-apply product. Alas, it did not work to remove even nominal fresh water boat scum -- with any oil residue -- from the Mississippi River. I went back to toilet bowl cleaner I've used before.

                  I had a dark rust stain on the cockpit floor after winter storage, probably from a roof leak in the storage building. I tried several cleaners which didn't help much. I dabbed the FSR in the spot, and it disappeared while I watched. Fifteen seconds tops.

                      Applied product with paint brush, allowed to sit 15-20 minutes, then used deck brush with a little detergent to wash down hull & rinsed with water. Had to apply 2nd application on a couple of stubborn spots, but it removed all of the brown river stains off of the boat. Beats the heck out of scrubbing with other compounds.

                        I do not normally write reviews, but this product is worth the time. A friend told me how great this product was – "just wipe it on the hull with a rag and rinse – and that is it!" He was correct. I applied the product to a hull who's previous owner had not cleaned the bottom in 2-3 years – the FSR made the fiberglass sparkled white again. After 10 days of floating in a river port, I used FSR to clean off the brown water stains/residues and the fiberglass sparkled once again. You do NOT need to scrub with this product, just apply and wash off – it is amazing. I have applied the FSR with a sponge mop and a wash brush. I pour a little FSR into a clean bucket, dip the brush/mop and apply to the entire hull - if you miss a spot you will see it after the hull dries. I like the wash brush application method best as it is easier to get the FSR gel completely around the chimes, through hulls, etc. with a couple quick passes of the brush. The FSR is normally dry after I get all the way around the hull. While probably not necessary, I then give the hull a quick wash/brush with boat soap. A rinse and you are done. It is very easy to remove water stains with this product.
