Thanks, Robbin. There are several clusters of them numbering about 900 or so. I am going to use citrus to clean off the old bottom paint and then use a barrier coat, #2000. Above the waterline I think some yellow tinted epoxy then some NuGlass to waterproof it.

Hi Tom those sure sound like blisters. Fresh water BTW is more aggressive than salt in the osmosis that forms blisters. So if you have not done a barrier coat you might think about it. Why they are above your boot stripe I cannot say. I had blisters on my M-17 in the stern port quarter that seemed to have resulted from the boat being wrapped. Anyway you can go look at the multitude of online information about blisters and repairing. Epoxy is what I used after grinding each out some. I have treated blisters on a compac, two of my M boats. It is not a huge deal but takes a little effort. Best of luck.

currently no M boats (but always looking), Marshal 22 & Gig Harbor Lobster Boat

While pressure washing the old bottom paint off my M17 I managed to dislodge hundreds of pencil eraser sized bits of the yellow gelcoat just above the boot top.All of the spots are round, like bubbles formed under the gelcoat were popped by the water jet. It almost seemed that there was some water migration along that line between the white boottop and the yellow hull. What is the best way to handle all the missing yellow gelcoat? The coat underneath is white and doesn't look like just a resin layer or fiberglas cloth weave. Anybody know what this second coat of material might be composed of? And how best to fill in all those holes? Would just making up some yellow gelcoat and troweling it into the holes work? I am not too worried about cosmetics at this point.I would just wet sand the patches and maybe coat everything with the "Glass" coating I used two years ago which has held up very well. I will be keeping the boat in a fresh water lake this year here in central Texas. Any ideas would be appreciated. Fair winds, Tom B.
