I have been using Super Ship Bottom for years now and could not be happier. My original coating was Micron CSC about 14 seasons ago. I did the annual touch up to cover the tattletale coat that was showing. On the 5th season I did Super Ship Bottom. It is a Multi-Season HARD Ablative. I have never had a barnacle grow on the boat ever. I do not get the boat powerwashed at the end of the season and simply let is remain for 4 years at a time. This is my 5th year on this last coat and I am going to have it powerwashed and then I am going to paint it. A gallon gets me around the hull twice and that is it. It is nice to not even have to look at the bottom of the boat for years at a time
The colors are not all that pretty but the paint lasts and the copper content is high. This season I am going to get a quart of Micron to do the area from the turn of the bilge to the boot stripe. Interlux paints are so good looking
Super Ship Bottom can be gotten from the MFG on the web for about 150 a gallon via the mail. It feels like cheap paint, not like velvet as Interlux paints do, and has to be mixed like crazy to get the copper off the bottom.
I highly recommend it and only do that because I have been using it with such great results and limited maintenace for so many years.
Good Luck
