Interlux VC Underwater Epoxy

VC Performance Epoxy is a two-part finish ideal for trailered or rack-stored performance powerboats and sailboats. Formerly known as VC Underwater Epoxy, it produces a hard, slick, semi-gloss white finish with special additives to make wet sanding and burnishing easy.

VC Performance's semi-gloss finish makes viewing sanded areas easier. It contains no antifouling biocide. Overcoats have a 10 minute drying time. It can left to dry indefinitely before launching. Use with 2316N thinner. Offers 200 Sq.Ft./Gal coverage when sprayed (220 Sq.Ft./Gal coverage when rolled or brushed).

Available in a Quart Kit (contains two quarts: 1 quart base & 1 quart curing agent) and a Gallon Kit (contains two gallons: 1 gallon base & 1 gallon curing agent).

Worked as advertised.


Great service by technical advisors at Jamestown Distributors. Made all the difference in the world.

I would buy this product again


Really too thin for rolling or bushing was really messy to apply by brush or roller. The next time I use the product I will spray it on. I liked the finish when applied to the bottom of our boat




Brush marks


For those of you complaining about the difficulty you can have rolling/tipping or just brushing this product...yes it is difficult. But READ the data sheet and it is very clear this coating was designed for spray application. Dont assume all paints or coatings are applied in the same manner.

Forget trying to roll and tip this stuff


I'm sure this is a great product, but was very disappointed with my results with rolling-on and tipping with a brush. Left huge grooves and was very difficult to apply an even layer. I'm done this process many times with other paints and never had this issue. Ended up having to sand away practically everything that I put on in order to get the finish smooth.

Easy to use


Use more 2316n thinner. Paint has a hard time flowing out.




I would buy this product again and agai


Tough coating put over Interprotec 2000e for trailered sailboat. Also adds additional protection against osmosis in fiberglass boats.

This is a great product!


Nothing beats the hardness of the two part mix for the bottom of a hull. I used this on the bottom of a stand up jet ski. I wanter sanded it and I now have a super smooth hull. This is a great product.

Excellent results!!!!


I used the VC Underwater epoxy when restoring a 1963 fiberglass Starcraft for my son. It is excellent paint for anyone wanting a hard, slick finish. I applied it with a standard spray gun using 40 psi. It went on perfect with no runs. Recoat after 15 minutes. I used 3 heavy coats and the finish is like factory gelcoat[...]Excellent product from an outstanding distributor.

Works great


It gets very hard very quickly therefore if you intend to sand it you must jump on it as soon as possible. To get the best possible spray surface finish it needs to be reduced 10 - 20% which is more than the tech sheet recommends.




Great to roll on with 4" foam.


Do your best prep work and the application will be smooth. 3 coats did a great job on my daysailer after many hours of sanding off old anti-fouling copper paint.
