Check the link below to Boat US article. Very informative. Just finished doing my hull and it turned out great and was 3 step process with the first step the most time consuming.
1). Use wax cleaner or compound. My boat was done in Spring, so we just used Collinite Fiberglass boat cleaner. Worked great and brought color back.
2). Polish boat. This is a step I always skipped in past but did this time and it made a big difference. Seems to smooth things out and make step 3 easier.
3). Apply wax by hand. This is the easiest step and we used Collinite Fleetwax paste. Awesome finish.
Don't let the polish or cleaner dry or it will be harder to remove. The Shurhold buffer works great!
