Product Details

Micron CSC is an great multi-season ablative bottom paint with a copper-copolymer formula that provides controlled release of antifouling biocides at the paint surface.

The longevity of the coating depends on the amount of paint applied. CSC retains its effectiveness even when the boat is removed from the water for extended periods (winter storage, for example). To reactivate come springtime, use a stiff brush or powerwash lightly. Suitable for sailboats and power boats.

Available in Black, Blue, Green, Red, and Shark White colors in Quart and Gallon sizes. Dark Blue is available in Gallon size only.

I would use this product
By Steve from Ann Arbor

Verified Purchase

Key to success was using a 1/8" foam epoxy roller. Do not over load the roller. Accomplished two coats on the hull of a 15 foot Boston whaler. I cut the roller in half. The consistency of the paint is somewhat gloppy if that makes sense. It does like to drip off the roller.

Bottom Line Yes, I would recommend to a friend

Product great but damaged
By KW from Machipongo, VA

Verified Purchase

Paint arrived without any obvious signs of damage to the outer package. Upon opening the package the can looked like it had been thrown from a moving vehicle. Dented to the point it would barely stand upright and leaking. Called about the situation but was only offered an empty can to put the paint in. I expected a little more considering the cost if this product. I did not pursue the issue since the job was time critical. I hope this product was not sent from the warehouse in this condition. Great product that I have used for years on commercial fishing boats just very disappointed in condition at receipt and minimal customer service response.

Bottom Line Yes, I would recommend to a friend

Works well in multiple coats
By Robert from East Moriches, New York

Verified Purchase

I used this bottom paint on a 16 foot sailboat that sits at a mooring in the water all summer. I can finish the whole bottom with a skeg and centerboard with just one quart, if thinned out a bit. Because it's so expensive, I have only used one quart per year. Every year, I rough up and clean the old paint with a scotch brite pad, and apply the new coat over the old one. Now that I have 3 years of buildup, this seems to keep the slime buildup off the hull a lot better. This paint stinks. Definitely use a respirator when applying.

Bottom Line Yes, I would recommend to a friend

yes,yes,yes, and probably yes
By Not another boat Bill from Lake Erie Islands

Verified Purchase

MY 31' Tiara's bottom was stripped and painted with black AwlGrip in 2005. That application lasted about five years without touch up. Then minor work was required yearly, mainly involving pinholes and small areas. Since I can't buy AwlGrip in quarts I went with CSC over 2000E barrier coat for touch up. I don't know if this is the method for professional shipyards, but it works for me. Fresh water Lake Erie is my boating location.

Bottom Line Yes, I would recommend to a friend
