    Is fiberglass matting necessary?

    im fabbing some enclosure for my comps right now. and i cannot, for the life of me, get the **** matting on. i tried tearing it as opposed to cutting it, but it just sticks to my gloves. i managed to get only a few small pieces on before the glass hardened and i couldnt go any further. do i even really need it? im only running 75wrms comps, so does it need to really be THAT strong. the first coat alone was pretty strong. it will take me like 10 years and $1,000 worth of wasted fiberglass before i'd even finish. TIA.

    Re: Is fiberglass matting necessary?

    Are you using the correct resin? It should stick fairly easy. Try "dabbing" resin on matting to get it started. The matting will turn clear or see through when its soaked. It usually isnt hard at all. What weight matting are you using? like 3/4 oz, 1.5 oz chop matte?

    Re: Is fiberglass matting necessary?

    sounds like you mixed your resin too hot sir. You should get at least 20 min of play out of it. Req's real good at glassing techniques........ (even though he didn't take any of my advice).haha. I've glassed quite a lot myself....

    quick hints I'll give ya.

    1-Your resin mixture should contain only 10-15 % catalyst. Obviously the more you use that faster it gets hard, and it may crack. But if you don't use enough it'll never dry.

    2- Cut out all of your stuff ahead of time before you try and lay it down. One technique that I like is cut bigger pieces of teh matt in the shape of what ever it is you're glassing, soak em up and layer them together. Making sure the matt really soaks up the resin. Then putting on one big piece over the entire area. Using a roller (in needed) to form it.

    Hope this helps a little.


    P.S........ Try to cut and trim your sh1t while the resin is still wet. It makes life a lot easier.

    i believe its the right resin. I think its Bondo brand. But i must have the wrong matting. Mine looks like a bunch of white straw mashed together. And how the heck do i get an accurate measurement of the hardener. i just did 14drops per ounce like the can says. thanx


    Thanx Bean, for the tips

    whatever the can says is perfect.

    bondo brand, however expensive, is fine.

    your matting, is fine.

    if you are trying to put the matting on and its sticking to your fingers, try not to get the resin on your gloves -

    one hand for the cup you hold, one hand for the brush. put a light coat over your area, and pick up a piece of matte (i like to rip pieces off, it conforms better to curves this way) and then put the glass down (without touching the resin with your gloves) and then use the brush to dab it into the resin and have it stick. then get some more resin on your brush, and paint the top. it should soak up (remembr the dabbing motion)

    you can put down several pieces of matte down at once as you get better at this - but do your best to keep the resin off your gloves, or change them when they get soiled (lol) so it dosnt stick to you as badly.

    ive gotten to a point, where i get literally NO resin on my hands while i work on a project, and i glassed my doors in about 15 minutes (2~3 layers)

    keep practicing, and you will get it down too. and bean, i dont really have a need for those ideas yet. when i do my RL-S box, i may try it

    i just dont see how it conforms to the kind of curves im playing with, and ATM - i dont need it that thick.

    yeah, that's where the strength comes from.

    can you send any pics of what you're trying to do? That always helps to make recomendations.

    Yes thats what gives you the strength. You should only need a few layers for kick panel. Keep trying mane.

    Re: Is fiberglass matting necessary?

    pix are a REAL pain in the ***. so im gonna hafta wait till i have time, i cant do it now.

    but as for the hardness, its pretty **** hard already with only 2 coats. so if the matting only serves for strength purposes, then i think ill be fine bypassing it. it doesnt prevent cracking or anything does it?

    phhhhh whatever.


    No, I think the problem is what's lost in the translation over the internet. You know what I mean? I can't describe well enough the technique. I wish I could show you in person, then it'd make perfect sense. Maybe when those dudes buy you a ticket to dallas! If they do, I'll at least buy you a beer.

    I don't work for beer, I work with it!

    haha you NEED the matting if it will be enclosing a speaker. I dont even think you can cal lit fiberglassing if you dont use fiberglass, it would just be resining... or something. Although it seems hard, you will probably get flexing with just resin. Trust me, slow down, take you time, and USE THE MAT!!!
