Okay, i've done a few fiberglass projects (kick panels, dash etc) but i havent done a speaker box yet. Right now i'm at the point where im ready to fiberglass.

Is there anything special i need to know? any tips or tricks you guys could pass on?

Also, Would it be okay to do say, 2 layers of fleece, then one layer of fiberglass, then repeat that process until its about a quarter inch thick? Or is that a no no? It's a big box so i'm tryin to keep the cost down, 5 bucks a bag for fiberglass is killin me!

Thanks.

you don't want to do any more layers of fleece. you want to build the rest with chop mat. if you go to a fiberglass supplier, they can give you a discount on the chop mat the more you buy. so if you are doing a lot of glassing, this is the way to go. you can also get resin in a 5 gallon. it is also cheaper that way. also the resin will ALWAYS be good. you wont waste your money at home depot. get home mix it put it on your project and have it take days to cure. the better the materials the better the finished product.

also plan ahead and do all layers of fiberglass at once, don't let a layer cure before adding another. I read that it won't bond properly and will end up being weaker than it should be, or even peeling.

i have heard about this problem but never had an issue with it myself. but just use a laminating resin or lay-up resin for doing your projects. the reason it might ni=ot stick it that finishing resin has wax in it. if you let it cure it you will have to sand it in between. the wax rises to the surface when it cures in the finishing resin.

I am not sure how true it is, but I've heard from the owner of Select Products that resin actually has a 90-day shelf life after its first openend. I have personally used resin that I have had longer than that, but I just wouldnt go so far as to say, that its ALWAYS going to be good. The chemicals that make up the resin, over time, will begin to seperate and not cure properly.

I heard that on the fiberglassing video that they offer.

that is true about the shelf life of resin.

i was refering to the resin always being good right from the start. the stuff from home depot can sit there for a long time before it is used. so it can be a gamble to buy. the stuff from select or other fiberglass suppliers is more fresh and you will actually get the full shelf life out of it.......and ps im really proud that you sat through the video.......those are really boring Some Questions... -- posted image.
