OffShoreOnly.com Boatshield $16.95 for a 12oz. bottle. It works awesome, I'm a big skeptic on new wax products and this was no exception. I tried it out on my truck and was very impressed. I normally use zymol but I have found that although the shine is great the carnuba formula in zymol tends to only last about a week and one wash before it is almost gone!!! With the Boat Shield it has held up through 3 washes already with no difference in appearance or slickness to touch.
It works on fiberglass/gelcoat/chrome/painted surfaces. Give it a try, I think you will find you are impressed. I was so impressed with the OffshoreOnly.com line that I picked up a distributorship for them. If you have any questions feel free to email me.
