    My Fiberglass Sub box

    Okay, here is my geto first time fiberglass sub box for the Matrix.
    Well, I want to thanks to all those who share their work and idea.
    Tutorial start from here http://web.njit.edu/~cas1383/proj/main/ and http://www.ajquick.com/cars/tutorials/fiberglass.php
    Thank pcmofo for the newbie boost
    Material from Lowes and Wally world.

    Tape the darn thing down.

    First layer

    2nd layer

    I skip taking picture after 2nd layer cuz it's really messy and I don't want to screw up the camera with my sticky hand.
    Here is the final box. Front and back shot.
    5 layer of mat + fleece.

    6 layers of mat + foil and tape


    Okay, it my first time every play with FG and could be the last. There are may bubble, but that okay as it a learning experience. I think it's strong enough because when I stand on it, it's safe and sound .

    Now, all I have to do is cover it with carpet. I was going to use left over fleece instead of buying carpet. What you guy think? Is it a way to go or doesn't mater and use what I have. I want fleece cuz I already have it and the color match with the back interior.

    6 layers is plenty strong, i wouldnt worry about that. Before you cover the front with carpet or fleece i would add some bondo to the front and smooth it all out, the surface looks very bumpy. as for using fleece instead of carpet...you can try it. if it looks like crap, then pull it off and use carpet.

    x2.

    Good work matrix. I got air bubbles the first time I did glass work, it turned out fine as long as you have 5+ layers, and not every layer has bubbles. I'd reccomend putting some deadner around/ in your box.

    But again, really a great job for your first time!

    Yup, Lowes has Elmers instead of Bondo resin and price is the same at Lowes vs Home Depot.

    Anyway, thanks for the tip.
    I end give the box a layer of light weight body filler (Bondo). Cuz I already had that stuff sitting on the shelf that I bought when I did the fab on the Supra and Matrix.
    Okay, so should I have the box a coat of primer or just adhensive spray and carpet/fleece over? I don't want the adhensive spray soften the Bondo filler.

    the adhesive won't do anything to the bondo. the only time you really need a primer is if you're going to be painting, or you're just trying to get the surface mirror smooth. in either case, if you've got your surface reasonably smooth with the bondo, you're good to go for fleece/carpet.

    get the super 77 spray adhesive.

    It's the best out there, bar none.

    Re the fleece, I'd use carpet if I were you.

    The fleece won't stand up to the abuses in the car as well. Things hitting it, snagging it, catching it, etc. Carpet won't wear as quickly.

    Looks extremelly good for a first enclosure! I think I can sense someone getting addicted! This stuff is like crack...

    makes you feel really good when it's all done and have someone ask you who you paid to have it built....THEN you'll really start to get addicted....

    ever played with Super 90? I think unless you're doing arts & crafts, it's the way to go. Holds like a motherphuccker.

    Thanks guys/gal. I already pickup 16oz 3M Super 77 from Wally world for 9 bucks.
    I used the can make by Loctite? before and it's okay but not the result I expected. I read that lot people use Super 77 for car's roof/ceiling so I assume it good to hold the carpet.

    Anyway, I just use a fleece for now. If that doesn't hold, I'll go with carpet. I choose fleece cuz I already had and match the color. As for it being beat up is not really a concern cuz I tent to take good care of my car. The only thing that often in the back is the stroller and/or a a box for groceries.
