    Can a bottom coating like interlux vc17r be used top side without detriment?

    Interlux vc17r is an anti-foiling, thin film style of paint. It uses a chemical compound to kill things that might want to live on it. Using it on the topsides of a yacht will expose crew to these poisons, so, I'd strongly recommend you not employ it as you plan. This paint is well known for it's smooth finish, but it's not for human contact.

    Huh ? The UV will burn it in weeks, anti fouling paint is soft. Topside paint is hard and UV resistant.

    Choose Polyurethane topside paint for long service life.

    What do you mean "topside without detriment"? Do you mean, can it be exposed just above the waterline when you have coated the bottom of your boat or do you mean as a topside colour paint?

    The answer to the first option is of course yes. The 2nd option is not advised - see the previous comments. Add in facts that it is expensive and doesn't give that good a finish for a topside.

    Are you just wanting a matt colour in the same shade? Use an auto basecoat/clear system. You can get matting additives for the clear. Not sure if they can make you a solid coat systems version ie a one can version (no basecoat).

    ps it will probably go streaky as well with the rain/dew to add to list of reasons not to do it.

    ps we painted 70m in matt black last year. I think you can get this in colours as well. From PPG. Some nano-pigmented paint. As used on some autos. It is a nightmare to paint on big areas but looks ace on your boat..or Mercedes:)

    Though this particular paint is fairly smooth, it's still full of poison and shouldn't be used on areas of the boat that will not be immersed continuously. In fact, if your boat is a trailer queen and doesn't spend extended stays on the water, then you don't need bottom paint (anti-fouling paint) on the boat at all. In short, use the appropriate paint (topside) or you run the health risks associated with being around chemicals designed to kill bio matter.
