Just thought this might interest some of you who keep your boat in the water- I have been using micrin extra the last couple of years with very good success and really no complaints. This year i saw the Petit trinidad antifouling bottom paint on sale and with the same qualities- ablative, slime inhibitor etc i decided to give it a try , especially since i had haeard many good things about it before. Well i wont throw away my money any more because there is no comparison- no barnacles on the hull per se but loaded with slime more so than i have ever seen on a boat bottom. the areas i did paint on my metal running gear were coated with barnacles even though they were painted as well. So in summary , i will never use the Petit antifouling bottom paints again.
