    Kawasaki 900 ZXI Fiberglass Hull Repair


    .

    I built a stand and flipped the ski to get a look at the bottom. Here are the pics after the first round of sanding.

    Here are some shots of the stand and hull before I started removing previous repairs. Water was getting in and some of the previous repair material could be pull away by hand. I've never done this type of repair, but my instincts tell me to remove all of the previous repair material and the purple paint up to the ridge in line with the lower edge of the sponsons. I want to keep the sweet 90's "JetSki" graphics. Any and all suggestions or tips are SINCERELY appreciated!! Next pics will show the repair materials, however, I don't yet have paint, and I believe that Steve said that it's paint, not gelcoat, and that Kawasaki had problems with this particular paint.

    The problem with the previous repairs is that the correct materials were NOT used. You need to use EPOXY resin, not the standard stuff.

    Start by stripping it back to bare glass and cleaning it REALLY well. You want to knock it back with 60 or 80 grit sandpaper once it is cleaned and wipe the whole thing down with acetone. Post pictures when you get to that point and we can figure out what you want to do for the bottom.

    As for saving the paint, remember that whatever repairs you need to do will more than likely add thickness to the bottom so you want to make sure that whatever you need to do, can be blended with the rest of the ski.

    Thanks! There are so many options....How about these products:

    Bondo Fiberglass Resin, 1 gallon

    https://shop.advanceautoparts.com/p/...m_content=ITEM

    Bondo Reinforced Fiberglass Filler ('kitty hair")

    https://shop.advanceautoparts.com/p/...m_content=ITEM

    Bondo Fiberglass Matt

    https://shop.advanceautoparts.com/p/...m_content=ITEM

    Sean: stripping it down to bare glass... is that exposing the fiberglass hair/fibers, or just getting all of the purple paint off and exposing the white?

    Obviously, where there was a previous repair, I have to take it down to the fibers, right?

    The purple is paint. There is white gelcoat underneath that. You need to get below the white gelcoat into the glass, which is sort of a bone color.

    Knock the paint off to where it is white/eggshell colored.

    The bondo stuf is really cheap and it is polyester resin so it won't stick properly to the kawasaki hull.

    I use the resin from us composites and it seems to work well. The peeps at x-h2o recommended it.

    End of day 1 with scraping and sanding. The side wall purple paint (and sweet "JetSki" graphics) seems intact. Thinking of stopping about where things are in the photos. Is it possible, and a good idea, to feather the edges of the existing paint and overlap the epoxy and new paint? I have to get off the intake grade and get access to the tunnel. I think due to the age of the ski, the purple paint was fairly easy to scrape off - much easier than trying to sand it. Just have to be patient and keep the blade from digging. I finished up with a wide chisel after running out of razor blades.

    Maybe tape a line and go with black Interlux paint - forget trying to match the existing, faded, purple.

    Sean: thinking this is the epoxy and hardener you suggested from US Composites, correct?

    That sounds like a better plan. When it's in the water you won't be able to see the black anyway.

    Check out 'smokeysevin's link 'JankyStandup' where you will see a WHOLE LOT of bodywork and repair stuff going on. DO NOT use standard fiberglass resin.
