    On my 03 40 Open There are a couple spots on the windshield frame that are corroding. The areas are around the wiper assembly and corners.
    Has anyone taken the frames apart to repair it? I am thinking that getting everything back together is going to be a real PITA.

    I took mine apart but could not find anyone to make new ones. Had a boat shop in Marathon repair what damage they could and they painted them, surprisingly easy to put back together.

    The aluminium windshields come from Taylormade - sane as the glass. I replaced some of mine as they still had parts in stock. For the rest, I had the corroded parts blasted and then had them built up with epoxy. They have lasted 4-5 years so far..

    American Marine Products in Pompano Beach,FL also made some for the luhrs like the 2006 36' open I deal with. We ended up pulling the entire windshield several years back and had it re-powder coated.......then some spots popped up again and recently had it sanded and painted in place. It wasn't too terrible to pull it and put it back. Pretty straight forward.

    I have aluminum frames for my back deck enclosure. Stripped and painted two years ago and now has big blistering bubbles. I am suspecting a galvanic issue. Wondering if a small zinc on each frame would make sense.

    If you pop a bubble you know fast enough, but my guess would be that the surface wasn't prepped well enough.

    Interaction probably with the wrong primer and not prepped correctly. Zinc Chromate primer is what you want, not sure what a small zinc on the frame would do in the air.

    Also had galvanic corrosion on aluminum frames from a steel snaps installed improperly by a canvas shop
    Pulled all steel screws/snaps, cleaned sanded and primed, then painted and used glue-on snaps for the canvas covers.
    Also tried with aluminum screws, but they were too soft and several snapped off.

    Zincs on the frames with protect only after you sink the boat, then you have to replace them twice a year. :cool:

    Well put and thanks for the chuckle. :D You have more faith in glue that I do, but as long as your canvas isn't too tight and you don't unsnap them too often you should be ok for awhile. If Oscarvan's problem is indeed galvanic corrosion he needs to separate the two metals. Easy enough to do. But my bet is still on the preparation before painting, or as J points out using the wrong primer.
