Just was curious if this stuff is worth the cash and effort, how long an application last. Also, I leave my boat in the water sometimes for a week or so, does it attract or deter any organic growth on the submerged areas.

if done properley, then yes it is worth it. it will last you the whole summer if not more,

I tried the dolpninite stuff similar to this and it helped a little, still left a yellow stain below water line. I have been thinking about trying Ineterlux's new stuff VC-17

A long time ago I tried to do a comparative ananalysis in the tech section. Do a search with my name. The results were a bit skewed because my motor was getting sick, but I did show a gain. The only question was how long it would last. Search for the thread. It had alot of good info.
