I would recommend "Coat It". I used it on bottom of my driftboat and found it works great, is seems to be "slicker" than gluvit and not as heavy. Very easy to apply, you can use your normal paint roller. I used 2 cans and total cost was @ $50.00. Just make sure you apply evenly and quickly as it sets up rather quick. One flaw is it does chip off over time, but all you need to do is apply a new coat. I just ordered a new Willie last week, and plan on putting this on the bottom as one of the first things I do to it.
