    Default Bilge area repair/clean up SST(Artie-Hal please respond)

    This is the bilge area of my new-to-me 1979 Sleekcraft SST20. My question is; how do i go about cleaning-up the horrible glass work in this area. Everything seems to be factory/un-repaired. My main issue is the transition from the top of the tunnel to the vertical piece going down to the bottom of bilge. It appears that the glass maybe shifted when they were trying to smooth it out(on top of tunnel) which made the ugly wave type of roll as it goes vertical. I believe it is structurally sound, just looks terrible(i am building this mainly for my dad/brother and dont want to give them something that looks like this) Can i/should i grind this wave off and re-glass? I was just going to put an engine and carpet in it and enjoy it, but about 3 days after i got it i saw Hal's Kona build, and that plan went out the window. I wont be able to do the exterior for years(funds), but i want to get everything inside done. I think i want to use epoxy. The time that you guys have spent to help the members of this board(and me already) is amazing and greatly appreciated!

    Grind,Grind, Grind and then Grind, Grind, Grind! Lol! I feel your pain.
    In all seriousness, the only real way to clean up that mess is to grind and sand until it is straight and flat, Yo have to get rid of any of the delaminated, loose flakey glass, to where you have solid laminate. Any thing that looks suspicious, like loose or flaking, cloudy, white spots and any thing that looks dry. Grind it down untill it is gone. If you have any low spots or grooves left behind, fill them back in with glass. CSM is a good filler and builder. Make sure you wet out thuroghly, and roll every thing down with tith a mat roller. build slightly high and take it don flat, with a grinder or air file.
    Depends on how far you are willing to go, and what your finnish is going to be. If you are covering with carpet, you dont have to be as pretty, just structurally sound, without any really beig bumps. If you are going to gel, then prep is every thing. Once you are happy with the straighness, you can fair with a good quality poly filler, or a resin, microballoons mixture for a filler.
    Just remember, you have to get rid of all the bad glass first, and then go from there. It just takes alot of grinding, filling, and sanding.
    If you are considering epoxy, then Artie is your man. He will be able to guide you in the right direction there. Just remenber, if you use epoxy, You will be maried to it for any future repairs......Hal

    once you grind all that nonsense out and slap some glass on it to fill in the holes you might want to take a peek at interlux "bilgekote" it goes on pretty thick and flows VERY nicely. cures rock hard and handles spills great. most of the time i dont even need any cleaner just a quick wipe.

    my before:



    my after:



    if you do end up using it, make sure you got some good ventilation. the fumes are intense!

    Thank you for the input guys.

    ah, got to love working on your boat with a shovel and a pry bar!!
    that came out very nice, i will definitely look into using that "bilgekote".

    might have to start another thread about re-mounting my saddle tanks.
    they are glassed in aluminum tanks like ka0tyk's and holorinhal's that have been in place for 34 years!
    they are between tunnel and side of boat and not really mounted, just sitting on old rotten 34 year old pieces of carpet.

    If they are the same tanks as mine they wont come out unless you remove the gunnel supports just in front of them so you can slide them forward than out. On mine I welded tabs to the tanks to bolt up to a new gunnel support instead of glassing them in.

    Thats what I was think about doing.
    did you just mount in front just to secure it(mount is not holding tank up at all,just holding it in place)?
    did you lay anything down for them to sit on?

    thanks for the input

    mine are sitting on my new carpet now with a gunnel support in the front and back thats glassed in and they're bolted thru those. then the 6" section of uscg fuel hose to the filler neck helps as well.
