Hmm, I'm trying to figure out WHY you would wan't to fiberglass over a wooden box? Or are you talking about a fiberglass one that needs repairs?

I've done a couple installs at work where the customer wanted fiberglass over the their sub box.. it still looks custom. If you have an enclosure built of MDF, then fiberglassed over the parts you see, you'll be paying a lot less money than if you wanted a complete fiberglass enclosure to go along with it.

One piece of advice:

Do not jump right in and try glassing the firstpiece ever to go in the car. Mess around with it on scrap pieces. Play with resin to MEKP(hardner) ratios, time hardening with each different ratio, play with matting techniques. Experiment with pretty much everything until you feel comfortable mixing and knowing how much work time you'll have. It'll save you money in the long run. It'll also save you from ruining a piece then having to rebuy it. Remember, practice is the best teacher. I can sit here and give you reference after reference, and things to read, but with glassing, experimentation, and hand's on work is the best teacher. Don't get frustrated, take your time, and you'll be pleased in the end. Good luck.

if you are jus tlooking to cover a box, you wont even need fiberglass!

if your box is about as perfect as it gets, and just needs some paint, then you can start with a filler primer, should be available at any auto body place in a spray can.

if the surface needs a bit of work, then bondo it is, again available at an autobody store. a lightweight bodyfiller will keep sanding time down, and a fat squeegee will ensure large plane surfaces stay flat and true,

after the filler, the primer will take care of any pinholeing, and get the surface ready for the paint.

you can use this concept for any surface really, and not just an MDF box.

watch out for corners, they can make aesthetics challenging in any situation.

and good luck!

to answer darklegacy's question, im going to build the frame of a box, and of course the mdf **** for the subs and poweramp, and fiberglass it. nothing to special, just a typical fibgerglass box.
