Well pulled the boat last Tuesday and found stuff called on off by MaryKate. Bought a gallon and did a test spot today on the starboard front. Sprayed it on with a RoundUp 1 gallon pump spray bottle and let it sit for a minute or two then rinsed with cold water from my garden hose. Got about 75% of it off so got a small scrub brush that I use for doing tires and very lightly scrubbed (really just 1 swipe with the brush) and rinsed and it was pretty clean. Probably would have been perfect but my boat at one time had bottom paint and there are still remnants of it and you can see some marking where the paint meets the gelcoat. I would love to get the rest of the bottom paint off but short of sanding I'm not sure how to.
Anyway, thumbs up for this product. I only did about 6-8' back from the bow on the starboard side and spent about 45 minutes or so on that. Tomorrow I am going to try power washing it first before using the on off to try to get most of it off first. I used about 1/4 of the gallon bottle so may need more. Guy at the marina said I would probably use just over 1/2 the bottle on a 25 'boat??? The directions say to brush it on so probably less waste if I did it that way. Just have to try to figure out how to get the area covered by the bunks without taking it off the trailer? Probably won't happen.
Power washing the stuff off after applying may be a better way too rather than a simple garden hose?
