Fiberglass

[mikegett]

I was shocked. I have needed a new place to buy fiberglass since moving this summer. Most of the car shops and lowes were charging around fourty dollars for a gallon. Car Quest even had it for 48. Autozone carries it for 24 dollars a gallon. Not bad since I was paying 20 from a marine shop.

What are the prices you are seeing for the actual fiberglass?

[turtles_ride]

I have access to all the stuff that people turn in on the hazardous waste collection days. I got gallons of paint and fiberglass comin out my ass, and an unlimited supply of the hardener as well. I just don't have much of the fiberglass matte, but you don't need much of that stuff anyways right?

[mikegett]

Sorry about that. I was writing about resin not fiberglass.

dood hook me up, fok......lol i need resin and hardener, for fiberglass matt i use fleece ;)

alright folks, fill me in here....where do i find actual fiberglass at? i guess i didnt realize theres two things...resin and the actual fiberglass....good thing i didnt start on my projects yet or else i mighta found some trouble.

[Silentalero]

no its not that

there is fiberglass resin, fiberglass matt, and fiberglass hardener

fiberglass matt = is either a special kinda matt u buy, or you can use fleece (thats what i used to make my backseat mold)

Fiberglass resin = is the actual chemical you mix in with a little hardener and pour or brush on the fiberglass matt.

Fiberglass hardener = is a smaller container and you put some fiberglass resin in a tub and pour a little hardener with it and then you mix it up and then put it on the matt after you stapled the shape u want

[mikegett]

How does fleese compare to mat? Is it cheaper or easier to work with. Mat may be durable but it comes apart easily when glassing. This also makes for more sanding. Where would be some good locations to purchase fleese?

[turtles_ride]

you can get fleece at any fabric shop, or at walmart, or if you wanna go real cheap go to a salvation army or used clothing shop and just buy some old coats. i thought the strands of fiberglass in the matte actually made the structures alot stronger though and this is why you should use the matte over any material. i also got rolls and rolls of fiberglass tape, it looks like masking tape but it has thin strands of fiberglass that peel off the tape backing. you put this stuff right on the resin after you've put it on your fleece and it adds strength to your enclosure. Then you put more resin ontop of it and keep layering it. the good thing about this tape is its really thin unlike the matte or fleece so it goes on curves really well because its more like a screen or like cheesecloth, then material or matte.

[mikegett]

Sounds like a good idea. I will have to try out the tape on the next door panel. Do you have any suggestions on how to layer layer the resin and matt? It falls apart very easily. If I brush on resin and then lay the matt, it doesn't soak through. I have to soak the matt and then layer it onto the form. I just wandered if there would be a more conservative manor for this.

[Silentalero]

/\ thats where fleece kicks in, just get a brush n soak the fleece...


and btw your strength of the mold doesnt come in the fiberglass, your strength comes in your backfiller

[turtles_ride]

i don't understand why backfiller is so important. The glass strands in the fiberglass matting are for added structural integrity. Think of trying to break a carrot in half as opposed to breaking a piece of celery, the strands make the celery less brittle. Also, i can't remember exactly, but i don't think either of the links on fiberglassing stuff mention anything about doing backfiller for extra strength, i may be wrong tho.

[Silentalero]

the fiberglass itself is to make a solid shape, the backfiller is what builds the strength becasue its tiger or kitty hair and its there to harden and support the mold from behind

[wy3134]

yo guys, hook me up with the fiberglass resin! im about to do a custom enclosure to replace my back seats and need all i can get! what would be the best process to go about doing this project? my preliminary idea was to lay out a design w/ tape and then put some fiberglass mat down, then just brush the fiberglass resin over that? what is the best backfiller and where can i get it? also where do i get those O rings for the subwoofers for the fiberglass enclosures? what im plannin to do is put the subs in the enclosure where the top part of the back seat is, then put the amp on the bottom part....any ideas/suggestions? thanks guys...

[Silentalero]

ummm to do a backseat mold is gonna be a bitch, trust me.

you need to buld a wood frame first, heres some prepics of mine, im gonna toss it all in today n snap some pics

[Silentalero]

outside view


btw ignore the gmci crap, its an old pic

[wy3134]

is there like a box underneath those subs?

[mikegett]

I think he is using the trunk for air volume.

[Silentalero]

no there is a box, ill take the whole assemlby out and take individule pics but here are stencil pics of the box

[Silentalero]

heres some building phase pics of the wood framing

[turtles_ride]

Nice silent, is that the fleece you used? or is that like spendexy material? How tight did you pull it cuz i heard it sags abit when you put the resin on it. I just ordered the material i'm gonna cover my custom boxes with, I'm gonna make them similar to wrighties, but use the same pattern as my roofliner and other interior pieces. I don't have any fiberglass matte, but i think i will use whatever you guys recommend as a first layer, then laydown some resin, then put the fiberglass tape stuff down ontop of it. Here's a pic of the material

[Silentalero]

doesnt work that way homie, lol

use a poop material to pour the fiberglass resin on becasue its gonna goup on there and my material was stapled tight so it didnt sag, becasue once ur resin hardens, ur foked.

u lay the fiberglass first, then once u sand and smooth it out, you rewrap it with a top material to match

[turtles_ride]

ya i know i pull the fleece poopy material tight, then plop on some resin and hardener, then i'm gonna put the fiberglass tape down in the resin while it's still wet. Let it harden and keep adding layers of resin and tape for strength. And i guess i'll get some of the spray in stuff since you recommend it as backfiller. I'll keep doin the layers for strength until its thick enough, then i'll bondo it and smooth it out a bit, then use the same sprayon glue as i did with my headliner and drop on the new material so it matches. Thats the right way of doing things isn't it?
