Excellent boat cleaner
I wasn't sure about this stuff until I saw what it did on a friends boat. It is really good, cleans off the yellowing at the waterline and sides. I had to do two coats at waterline but it went on easily and washes off. I would recommend it to others.

Need another bottle.
Very surprised indeed. I left mine on for 20 mins and it work very well. for stubborn grime leave on for half hour and use a good stiff brush as you hose it down.

Brilliant Stuff
Best cleaner I've tried by far, took away all the yellowing from the gel coat and has left the boat looking like new. Once applied, leave on for half an hour/45 mins then wash off, simple as.

This product is particulaly good for removing rust stains from GRP, without using elbow grease. Simply follow the instructions and the stain disappears.

Good stuff
Tried it on a bit of my GRP and it did seem to do the job, but I had to paint it on neat.
