Gonna build a large fiberglass box, I'm going to build it into my trunk, it maybe up to 20 cubic feet in size. It needs to bond to wood, but not my trunk. (incase I ever need to remove it) It needs to be strong. It needs to be smooth so I can paint it with a black paint and have it look "perfect".
So, with that in mind, here is what I am looking for from this site (they're located about 150 miles away): http://www.shopmaninc.com/
To start with, on this page ( http://uscomposites.com/mat.html ) I was looking for the right size of fiberglass I should get...with the idea of using epoxy resin so that it bonds to wood well. I thought 3/4 ounces per sq foot/6.75 ounces per square yard was good, right? How many yards do you think I'll need for the 20 cube box?
Next, the resin...( http://uscomposites.com/epoxy.html ) I am not sure what to get, but here's a picture, I'm new but can learn fast, I live in florida so it's hot, and wet, humidity outside is like 70-100% most of the time, on a "good" summer day. I'd also be nice if it was easy to mix the resin and hardener so that there is little measuring. I also don't know how many gallons to get.
After that, page " http://uscomposites.com/adhesives.html " I was going to do a little carpeting in the trunk and thought about getting some #77 spray, yes no?
Also, page " http://uscomposites.com/fillers.html ", I need to make this sucker smooth, I was considering just buying bondo/primer and not worrying about mixing all that crap, but if it is a good idea I'll get some supplies so I can get a perfectly smooth finish for painting...I don't know where to go on this one...
Next, " http://www.shopmaninc.com/brushes.html ", Brushes, ah brushes...I was going to probably get a box or two of 1 1/2" brushes, 1 or 2 box of 1 1/2", yes no? And then a pack of squeegies.

1- epoxy resin is great stuff but it costs more than polyester and usually takes longer to harden. polyester resin usually fills the bill.
2-3m 77 isn't going to cut it in Florida.Its a really tacky glue but in your heat and humidity it doesn't hold to well in the long run. Try finding a local upholstery supply shop and pick up some high temp landau spray glue. or get 3m super 99 spray glue.
3- definately get a respirator.
4- unless you have all the supplies and tools, get the box as smoth as you can with fillers (bondo, rage gold etc) then send it off to a good paint shop so it can get a high build primer shot as well as a sealer and painted.
good luck

MDF is very porous. Any type of resin will stick to it. I use the cheapest resin that US Composites sells.
The paper cups you are buying--you can get those at wal-mart.
Don't use "bondo" brand body filler. I've never had any luck with it. There are several brands. I use a 3M micro lite.
I would not use 3m glue at all. There is some glue at Home Depot that comes in a metal can with a red label. The name escapes me right now, but I use it in Alabama and have had no issues.

That would be Daps weldwood contact cement.
Everytime I've tried brushing it on, I didn't have much luck. Maybe I didn't wait long enough for it to set and everytime I tried shooting it through a gun it would clog up.
I ditched that stuff and now use a ready spray vinyl/landau top glue for vinyl wrapping and complex curves/seams on carpet For carpet panels I use a high temp headliner spray glue.
