Thanks, Bama for the compliment.
This is from the Collinite website, FAQs page:
Should I always apply one of your cleaners (920 Fiberglass Boat Cleaner or 840 Prewax Cleaner) before waxing?
It is not always necessary. Take a look at each scenario, depending on if you are working on your car or boat.
Boat: If it is older (more than 6 years) and has any oxidation, dirt or film embedded in the paint, use the cleaner first, then apply the wax. If the paint appears to be clean after a wash, then simply apply the wax and skip the cleaner. Collinite also makes a one-step formula called the #870 Liquid Fleetwax, which is a cleaner-wax combo. Its durability is not as strong as cleaning and waxing separately, but you will still get 2-3 months out of it. Also, if you have a larger boat (25+ ft.), it is a nice time saving option to have, which is why it is Collinite’s #1 seller in the Marine Industry.
I've always used the 920 followed by the 925 (2 times/year). I don't go crazy with the cleaner - just a light application followed by a buff (wipe on/wipe off). The 925 wax instructions state that it works best when the hull is prepped with the 920 cleaner. I've been doing this since the boat was new and it ALWAYS gives a shine like those pics. Right now the boat is in Pensacola at the NAS marina. We had to take it a couple of months ago to the local GW dealer to get the freshwater pump changed. The guys in the shop there told us it looked the same or better than the new ones!
BTW, we ALWAYS give it a fresh water rinse (yes after every trip) and frequently wash with a mild solution of OrPine soap, as needed. We also keep it covered. That might seem a little anal to some, but I want this boat to be a keeper!
