Will buy again.
Awesome stuff. Easy on and off and it will make black gel coat shine like crazy. I have a 20 foot boat and only used 1/4 of the bottle.

Finally, perfect results in half the time!
I've tried absolutely everything to restore and maintain the gelcoat on my 87 Searay 340EC, and nothing worked as well as the Marine 31 products. Was completely satisfied with their multi step system and was referred to their One step product while talking to their customer support techs who offered a tip on removing final wax residue. Expensive, but it performs as described and in half the time than it takes for the multi step. I used a 12 inch wool pad and buffer. First apply with foam pad. Hardly any residue. Didn't take much product as well and may last me two summers.

Great One Step Product!
This stuff is a great single step replacement for compounding and waxing the gel coat. I have a porter cable polisher I usually break out but even just applying this by hand a using minimal effort it fills in fine scratches and restores the shine.

The marine 31 is the BOMB!! I've had my boat for 20 years and these products are the REAL DEAL.
The compound and polish brought my faded boat right back to its glory on the first try and the vinyl cleaner!! don't even waste your time trying other products if you value your time and money period!!
