    Fiberglass problem!

    ok i made my base for 4 kicker L7's rings. etc... ok i wrapped it with fleece no problem, resined it and did two coats even. come out and its dry but isnt stiff, so i cut out my holes to get to the inside to stiffen i thought and the rings start to sag. so i just put some braces back up to hold the rings in place. Now what do i do? keep putting resisn on the inside to stiffen completely or what?

    you sure its completely bone dry? try putting a hot batch of resin over it all (IE. add double the amount of required hardner, and throw that resin on there FAST). it may help cure the FG

    you used fiberglass mat/cloth, right?

    Re: Fiberglass problem!

    The way I read this it doesn't sound like you used fiberglass just fleece and resin? maybe i misunderstood that, but if you only used fleece and resin it's not going to be very stiff.

    Re: Fiberglass problem!

    If you can i guess you can put fiberglass on the backside it would make it way easier to get the outside smooth. The fiberglass will make worlds of difference, it will greatly strenghten the enclosure. how r u planning on finishing this box, carpet, vinyl, paint?

    Re: Fiberglass problem!

    Just make sure you get the entire inside glassed properly, after it hardens you can push on the outside to find your weak spots. you will be alot happier not having to smooth it out over fiberglass. I'm building a center console and next a sub box, both out of fiberglass, and it is a pain in the @$$ to get it smooth, but it will be worth it.

    Re: Fiberglass problem!

    Fleece alone will be decently stiff. At least enough to hold up some rings. But over a large span, it probally isn't strong enough to hold up 4 L7 rings with no center braces.
    I would see about adding a brace or 2 to bring it back to the original spot you intended. The add mat on the inside to make it sturdy. ALOT of mat.
    I would do about 5 and then a nice thick layer of thixotropic mix.
    Then just sand the outside some, body filler it and then prime and paint.

    Good luck.




    PICS??????





    The bitter after-taste of a poor quality job will last far longer than
    the sweetness of that cheap price!
