Well, tomorrow after work i'm diving into my first fiberglassing project.
As a preliminary project, before i build my speaker pods, i'm building simple flush covers for the rear doors, where nasty huge chunks of the door were cut out to fit my type-r's, so the entire door pocket and speaker area are gong to be fleeced, and i'm gonna make a nice cover, which will be finished with bedliner for a nice black rubberized finish, as well as underlay the entire back of the door once the covers are installed to make the doors watertight, as well as quiet as possible.
Seems like an easy 1st project, but i had a few quick questions before i go to the store after work.
I've noticed there's a lot of different types of fiberglass mat. There's LOTS of different weights of woven mat, there's 'chopped' mat, there's woven roving (which looks like carbon-fiber) unidirectional woven mat, and a few others i couldn't keep track of.
Which type of mat do i want for both my projects? I'm guessing the woven stuff, but what weight? I don't even know the difference. I'm guessing heavier is harder to work with, but needs less plys, and lighter conforms to curves better, but requires lots and lots of plys..... What mat, exactly, have some of you used with good results?
Also, i had a question about fleecing. What is the main purpose for fleecing? If you had thin enough fiberglass, couldn't you just use a solid sheet of fiberglass for the skeleton, and then fiberglass on top of that? Or does the fleece retain it's rigidity when re-wet better than the cloth itself?
Just curious, it would save me a second trip to jo-ann's.
Thanks, i'll be checking back.
