Did not get a chance to try it out yet, but I'll certainly pony up the $20 for the 16 oz bottle to see how it good works. Definitely interested in the transom cleaner, damn 525 is not putting out as much soot as it did but it still gets dirty.
This (http://www.washwax.com/) is what we currently use for the boat. Works really well. Only problem is it is a two-step process.
