Just finishing up a moderately complex fiberglassing project for my '00 Mustang. While fiberglass, matts, bondo, and such are relatively cheap, for most projects you will need quite a bit of it.
I'm photographing the stages and making some notes to post when my job is completed, but it is nowhere on the scale of what's in this thread. However, I still have a fairly large amount of $$ invested (probably a good $500+ just for fabrication materials), not to mention six full days of work, with an assistant.
I'm making a speaker box, amp rack, two front pods and a rear deck panel.
Materials used include:
Huge amounts of fiberglass resin (four 1/2 of the large cans).
Huge amounts of bondo (almost four of the large cans).
Filler putty.
Many cans of primer, paint, and spray foam.
A sheet of plexiglass.
A sheet of oak plywood (for parts of the amp rack and sub-box).
A sheet of MDF (for component baffles).
Carpet (for the front pods).
Many packages of fiberglass cloth and mesh/matt/whatever.
Tools that I can't live without:
Skillsaw
Rotozip
Electric Drill/Screwdriver
Jigsaw
Rotary Sander (the god of all tools for car audio work).
Non-expensive stuff:
Cardboard.
Duct tape. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
Metal Yardstick.
Level.
Exacto Knife.
Scissors.
Mission critical stuff:
A very understanding fiance'.
Hopefully, that gives a better idea just what is involved in this kind of work, but don't be discouraged. It's incredibly fun and rewarding as you see everything go from hideously ugly (tape wrapped around expanding foam covered in raw fiberglass is not pretty) to hopefully "wow, that's sweet!". It's addictive. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
