By his pics i would say it works great. The problem for me is its over $30 a quart, and seems to take alot of product to get the results he got. Not to mention they push the "pre-treater" at $30 a quart too. Woody wax seems to be a good product as well.

I guess everything is more expensive when it has anything to do with a "marine" application. Its going to take me a little while to get used to that.
