Does anyone know of any product that would inhibit marine growth on surface mounted LED underwater lights? Thanks
I'm not sure when the boats in the water, but if and when it is hauled out, the hull wax that has teflon in it really works at keeping most of it at bay on hulls ,as I have seen this first hand, I had a 26 ft and waxed the hull every year,I could not get to an area along the side because of the trailer guide on, and then after a month in the water I noticed a brown spot the size of the guide on, on the side, that I could not get too, so when it's out for its seasonal checks or storage, apply a few good coats of that wax and you should be good to just giving it a good rub with a rag after sitting in the water ,should remove the growth, hope this helps and good luck :-)
Check out this article in which we tested an antifouling wax:
I'd also go overboard and scrub them with a brush periodically, a practice we recommend you do to check on your boats growth and fittings anyway. We know its not always possible, but a mask and fins and an hour spent anchored in shallow water mid-season is maintenance time well-spent in our view.
