Bottom paint

I used to use interlux Micron CSC, but switched to Petit Hydrocoat a few years back. Both are ablative style paints. The hydrocoat is a little less money and seems to go on a little easier for some reason, and is holding up well (keep in mind my boat is in fresh water for only 5 months per year)
I have heard that Sea Ray uses Hydrocoat at the factory, if that is worth anything. For my use, I apply 2 coats once every three years, and do just the waterline every year to give it that clean, just painted look at relaunch.
 
Hey ARTIEB1,

Pettit and Micron are the leading bottom paints as of right now.

I'm actually a sophomore in high school (the boat is my family's), and I just did a project on bottom paints, and how they affect marine organisms. After much research, I narrowed the paints to test down to three: Pettit, Micron, and ePaint (an "environmentally friendly" option). After extensive testing, I concluded that all three paints, including ePaint severely harmed marine organisms around them. This shows that not all "environmentally friendly" products are options that are worthwhile if you actually do care about the environment.

Anyway, a boat has to be bottom painted, whether it harms the marine ecosystem or not.

Go with Pettit or Micron. :thumbsup:
 
I hate to be a noob. . . but isn't the entire point of bottom paint to be "harmful" to marine organisms?

I problem I have had with outdrive paints that I have had in the past is that they are not harmful ENOUGH to organisms!

Haha, good question. An antifouling paint (bottom paint) should repel organisms such as barnacles, tube worms, etc and prevent them from attaching to boat hulls, but it should not be harmful to harmless marine life that does not attach to boat hulls (copepods), such as marine organisms that are just simply passing underneath the vessel. :thumbsup:
 
I use the cheapest (least expensive) ablative paint I can buy, that has the same amount of coper that the major brands have... Sometimes its Pettit and sometime West Marine brand... I used to use the Micron CSC, but it is too expensive now...
 
I also buy the "cheapest" ablative . . . and it seems to last the 5-7 monthes the boat is in the water.

I used to buy the more expensive (high copper) non-ablative for the blowboat, which would spend 18 months in the water, but the last time I painted the boat that paint wasn't available, so I switched to the cheap ablative and kept my fingers crossed. The results when I pulled the boat last November were surprisingly good.

Outdrive paint is a different story. I used to use standard sprays -> one can per drive; and the results were pathetic. Last year, I used the brush on TriLux 33 on the drives. . .and they looked great at the end of the year. BUT. . I also noticed that the barnacle growth on my unpainted props was far lower than previous years. .so I don't know if my positive experience was biased by environmental conditions.
