Thanks for the comments so far. No one has used Awlgrip? I was kind of leaning that way, but hoping for some comments from folks with experience. I have looked at a couple boats stored near me with Kiwigrip, and while I like the look, it looks hard to keep clean. Perhaps the fact that the boat I saw it on was dirty just gave me that impression? My concern about using sand is I am afraid I will never get uniform distribution, and I hate how it looks when it is heavy in one spot, thin in another. I guess that's why I was leaning toward something where the grit is suspended in the product, or something like the Kiwi.
