When we bought our last boat a 13 year old Hunter
335 I went a differnt route
. I used to work at an auto restoration
shop ans saw the amounts of material that buffing and polishing remove. To get a long lasting effective polish the gel coat has to cut and cleaned down the the lowest pore that holds the chalk.
Since there was no physical damage to the gel coat, ie scratches that minor spot buffing couldn't fix, I tried a product that another friend had used.
Island Girl has a multi step cleaning
and wax system. It has a non abrasive cleaner that goes into the poeres and lifts the chalk out and reconditons and brightens as well. The wax goes on without rubbing and two coats made it look like water
and 3 was awesome.
The more sun the better the process works, compared to waxing and polishing it is fairly low effort. No hard rubbing.
After completing the finish on our boat at the end of the season people couldn't belive out boat was 13 years old.
The finish doesn't yellow or peal like some others. Practical Sailor did a review and it and Poliglow were rated at the top. After a year it still beaded water
and was very easy to recoat and clean!
PS: we love this stuff and no I don't own stock in the company.
