I'm building a set of speaker boxes for my 66 chevy truck. I'm doing it by making a frame first then covering it with cloth, spreading bondo on it and shaping it to what I want. The thing is "What is the right material to use when doing this?" It has to be able to be stretched to form the shape I want, but doesn't relax when it gets wet.

My brother is doing some speaker pods for my doors right now. He used a few old t shirts, stretched and stapled to a wooden frame. Once you stretch and stape them, then you can lay your fiberglass on them. if its tight enough, the material should not move.

Most use fleece. T'shirts also work. You can get it at places like JoAnn Fabrics or other places that sells material like your mom or grandma used to sew with. Maybe some of the hobby stores also. Then you want to get a can of fiberglass resin to coat it with. After that dries, then you can use the bondo to shape and fill in the voids.

I wondered about the fiberglass resin. I seen it done with it and I seen it done without it. I know I have some resin kicking around in the garage. Great and for Tshirts I have a Crap load of them for old rags. Thanks guys I appreciate the info.

When you get around to doing this take some pictures? Im not visualizing how this works or can I get a link to some pictures of some?

I'll ask my brother if he has any pics tomorrow when I'm there. The problem with using a fleece is that if its too heavy, it takes too much resin to soak it. That makes the piece more fragile than a few layers of t shirt. Its also thicker, so it makes it a little harder to shape around corners cleanly.

If you use the fleece, use the thin stuff or you will be using tons of resin.

I just finished stretching a couple of old t-shirts over the frame and the end pieces. I don't have any hardner for the resin so off to town I go to get some. Tomorrow I'll attempt the frame with the resin. I'm putting the pics in my journal as soon as I'm done here.
