Long ago the Awlgrip folks said do not wax their Awlgrip surfaces as the paint is so hard that dirt will not easily attach to it, but wax will attract dirt. Then they came out with the two products mentioned above for cleaning and preserving (the sun can chew on their special wax instead of the paint surface). That pretty much answers your question. Someone mentioned sanding. You can sand Awlgrip, but you would only do that for repairs, or as a last result before a needed repaint if the hull were terribly oxidized. But, you really want to use the right sandpaper, right compounds - all designed especially for paints and not fiberglass (too agressive). 3M makes a bunch of products to do just that, but usually you don't find that stuff on anyone's shelf. It is in the shop of the pro who understands the products and procedures. The original Awlgrip was very hard when cured. You only had about a 3 day window to fix sags, runs, orange peel, etc. after a paint job. Then came Awlcraft, which is a softer paint and more repairable - something that can be sanded and buffed long after it has cured which makes it a lot easier to blend in paint patches after repairing scratches, etc. But, actually now there are wonderful products on the market designed after much more R&D where you can work on the original very hard Awlgrip too, but like I said, these products are not easily found on the consumer market.
