Fiberglass

Once it is warm enough and I can get the supplies from a store, I thought I might try doing some fiberglass for my roof liner.  I have never done fiberglass so any tips would be appreciated.  At this point (and I am probably wrong again) I figure I can cover the outside of my roof with something like aluminum foil or saran wrap or something to keep the moisture from seeping through.  Then slap on some fiberglass and let it harden and then after it dries, I can remove it, cut off the excess and fit it inside the roof.  Keep in mind, in my Tudor, I only have to go around the outside edges of the roof since the main part of the roof is vinyl.  So with all the knowledge surrounding me here, where am I way off base this time ?  It sounds like it could work to me but like I said, I've never done fiberglass before.  Is this idea feasible ?  It would be fairly light, right ?  And I could later apply vinyl with a backing behind it, right ?  The spray foam idea sucked.  I'm just trying to figure out all of my options for my first attempt at a headliner.  Is fiberglass expensive ?  I don't think I'd need a lot.  I watched a video of a custom shop in Los Angeles doing a roof liner for Sylvester Stallone and they used fiberglass.  So much to learn.  But I'm trying.

I have used bees wax to stop it from sticking.

Thank you Smokin Joe. Would bees wax be hard to get off the paint ?

one handy thing I discovered years ago is that the old box of vinyl floor tiles you're never going to use make great mixing boards for body filler and fiberglass
easy to scrape clean enough to reuse too..

 

if you have some of the old 60's vinyl / asbestos floor tiles they make a beautiful and tuff / fire resistant bench surface for your wooden work bench top and they last for years and years

 

don't let the asbestos part scare you .. it's bonded to the vinyl ..ain't goin no place

You can buy a releasing agent that you spray on.
It would give smoother results rather than using something that will be wrinkled.
Also, the piece that you will remove from the outside will be larger than what is needed inside.

All good to know. Thank you everyone. Boy the stuff we have to learn to build a rod takes us into every known medium. This is so cool.

For an inexpensive mold release, try spray on, 'Hair Spray'. I think the stuff I got last time was the OV5 stuff. Get the cheapest stuff you can find, it will have the most solids in it. Hair spray is water soluble, so just wet it down with a hose or wet rag when it's time to take things apart. Dribble water along the edge of your fiberglass seam and let it creep back under. A bit of air pressure at the same time will help lift the fiberglass off of the mold. If you can wax the mold first, (100% carnauba wax is the best, the resin won't attack it) then spray the mold release, it will seperate quite nicely for you. You can always give it a little practice run with something before hand to see how it all works.

Don't forget gel coat.

OK, a lot to fathom for me. I am not concerned about a smooth finish or being too large. The finish will be hidden under batting and vinyl and as for size, I am more concerned with shape and I can cut it down to size to fit once I have the shape. Do I need a gel coat (whatever that is) if it won't be seen ? As I say, all I need is the shape. I love the idea of a practice run on something. Excellent idea. Unless you advise against it, I would like to try covering the panels in saran wrap and/or aluminum foil. That way any run off can be caught in a small trough I could make in the foil so spillage doesn't run down the side of the car. It doesn't matter about the foil or saran wrap sticking to the fiberglass. It won't be seen. I communicated with a gentleman in California at Tap Plastics who specializes in fiberglass. He suggested I lay a coat of speaker fabric over the panel and then coat it with Bond coat polyester resin. Can I buy bond coat polyester resin here in Canada ? Anyway, he said to first apply the speaker fabric, then brush on bond coat polyester, then add the fiberglass and bond coat that as well. Let it dry and job done. So I contacted Kawartha TV and Stereo to see if they carry speaker fabric but no luck. I'm wondering if any porous fabric will do ? To sum up, maybe I am way off base with saran wrap and/or aluminum foil but a practice piece sounds very wise. Does this all sound absurd to everyone ? I thought a thin, resilient but firm fiberglass headliner made sense. Opinions greatly appreciated. Thank you all.

amazon.ca is your friend. They deliver without any contact and they have hundreds of listings for speaker fabric on the site.

A wealth of knowledge is to be found here. How did you line Dog Spit ? I remember looking at how nice the inside was. I will check out amazon.ca for speaker fabric. Thank you Warren.

I did a mold with burlap instead of fiberglass mat. You would never know the difference strength wise. I have yet to pull any part from it, but it acts just like fiberglass mat would. Inexpensive to buy, you can get it in a roll in fairly wide widths if needed. Garden centers carry it, big box stores too if any are open.

gel coat is for a fine outer finish
if doing inner structural pieces that never show you don't need it

gel coat IS what you're looking at when you see a fiberglass boat

by that token ..NEVER sand it off something you're working on as it seals the surface of the fiberglass so your paint dosent sink into it like water on a sponge

I wish I knew about the burlap before I ordered the fiberglass but it's all a learning experience. And now I know that I don't need gel coat. That will save a few bucks. All that's left is to sort out which polyester resin to buy and where to get it. Micheal's might be a good place to start ? Thank you everyone for all of your advice once again. I never thought a hot rod build involved so many different mediums and I'm still just scratching the surface.

I'm just throwing this out there, what about commercial landscape fabric?

Well I've reached that point long past what we call embarrassing and rightfully so. I should have realized some time ago, just check Amazon. Thank you Warren for being so patient with me. I must frustrate you with my ignorance. Incredibly slow more often than not. And thank you Iwannagofast. I imagine landscape fabric might do but fiberglass really wasn't all that expensive. It might even be less than landscape fabric. Now if the weather would just cooperate. Oh well, lots of other stuff to do in the meantime. But first things first - Amazon ! Thank you again. So kind.

another thing that works good for fiberglassing is one of those blankets that's kind of fussy and very light. I'm not sure of the name.
