    Blaster 2 hull patch -- any advice?

    I am about to go to work on a couple of below-the-water dings on the WBII and any heads-up you can give me would be appreciated. Is there anything special I should know about this hull re: using polyester vs. epoxy resin, sanding, painting, etc? I am assuming this ski has a regular fiberglass and gelcoat construction, but obviously I'm a 'glassing noob.

    There's one dime-sized circle where the gelcoat has been dimpled on the rear, and a more noticable gouge at the bow. The gelcoat is missing from about a 1" x 4" area, and it goes down into the fiberglass perhaps 4 to 5 centemeters. It doesn't take on water, but has a bodged patch job by the previous owner using some ugly patch compound of unknown origin.

    I'll try to put up some pics tonight or tomorrow.
    Thanks again in advance.

    I am fairly certain that you are dealing with smc. that means you have to use epoxy resin, like west systems, and then paint. For filling small gouges, marine tex works well.

    Pics

    Here are some pics of what I'm dealing with. As you can see, the big gouge has had not one but two different patch jobs. Obviously, neither one held real well. (DISCLAIMER: Bought the ski like this! Not my bodgery!)

    There is also a third spot on the left chine I'd forgotten about. It's circled along with the one one bow in one of the photos.

    I don't know, from looking at the interior of the hull, it sure looks like fiberglass to my (untrained) eye.

    looks like glass to me also SMC is smooth I would hit those gouges with a grinder to open them up a little and just go for the conventional fiberglas repair! color matching will be the hard part IMHO Z
