What ratio are you guys mixing this stuff. eg. aerosil 3 parts, resin 1 part. And also are you guys mixing chopped strand in with the mix or just resin and aerosil.
Thanks for the help in advance.

I cant remember what the mix is I want to say 2 parts aerosil for 1 part resin, I do know that its just the aerosil and resin, if thats what your using. You can do a search and find the mixture for sure I know its ben talked about. I'm pretty sure that thats right though. ------------- Learning the trade one fiberglass creation at a time!

it depends on the consistancy that you want. a good place to start is for 500 mL or resin i usually put about a quart or additive in it.....i use the 1 quart paint mixing cups for resin and the additives. just start with a 2:1 additive to resin mix and that will get you close to where you wanna be. make sure to mix it really good and let it sit for about 15-30 minutes before you use it so the resin soaks up to the additive.

15-30 minutes before you apply it?????????? Will the resin not harden if you wait that long??????????? ------------- Learning the trade one fiberglass creation at a time!

15 -30, then add hardener

Ok guys the mixture i ended up using was just less then 4 parts cabosil to 1 part resin. This seemed to work really well. Nice and thick it came out to almost 1/2"
Thanks for alll the help and replies

ok i like how everything works, heres what i did, mixed it all up and forgot to add the hardener. Well i added the mix to the enclosure before realizing to add hardener. I got as much out as possible and then added hardener to that. Then i used a heat gun to try and cure it faster, by doing that did i compomise the integrity of the enclosure.

Yes using a heat gun can reduce the strength. When using a heat gun it cures quicker but acts the same way it would if you overcatylized it. it cures too quick causing the resin to be more brittle than it should be.

When I use cabosil/resin mix, I just add cabosil until I get a thick enough paste which is still easy enough to spread around..after a few tries, you will know what consistancy you want depending on the application.  ------------- Im a fiberglass whore!!

Can someone explain to me what this is used for exactly? Just to make resin less fluid like so it hardens better?

Well you can use it as something to build a certain area real fast. Or you can line a sub box with it. Supposedly you can mix it into the resin and let it sit for about 15 minutes or so and soak up the resin. Then put your hardener in it and this stuff is about as thick as peanut butter, so you spread around on the inside of the box. You can make it like a 1/2" thick. So all you have to do is fleece your box, resin the fleece, and put this stuff inside and you're done.

It's also good if your working in odd situations. Like upside down. ------------- Nik

I'm just curious, can cabosil be used when making, lets say, a spare tire well enclosure? Would you first create the mold with the fibeerglass mat and resin? or would you just use the resin and cabosil? When using cabosil are you completely eliminating the need for fiberglass?

Your not eliminating the need. Your cutting corners. I really don't recomend things like cabosil or polycrete or any other cuncoction in making a speaker box. They might be ok for use in things that don't need as much structure but I wouldn't use them in speakerboxes. At least not without already having enough fiberglass down to be strong enough by itself and then whats the point? ------------- Nik

just wondering, would 10lbs of fiberglass cloth and mat ( an unspecified mixture of both) be enough to make an enclosure for 2 10's?? The mat is 1.5oz/ft and the cloth is unidirectional 21oz/yrd. would thhat be a good amount to use? would i need more or less/

Well, that cloth is some pretty strong sh*t. I don't know the size of your box but I would say that should most likely do it. ------------- Nik

oonikfraleyoo....... you are saying that using a pruduct how it is intended is cutting corners??? or is it just because it is not the conventional way of doing it because it saves time?
resin additives have been around for a long time and are used for saving time and money. they also are around for specific needs such as verticle and upsidedown layering. granted they are not specifically made for the car audio industry, but then again what install product of this nature is???
oh and you better make a call to JL and tell them they need to think of a better way to join the 2 halves of their stealth boxes because they are doing it wrong.

It's fine for use if there is no other way. It IS cutting coroners. I am well aware that they have been used for quite some time and I use them myself but you should not use them in a project that requires high strength. They are plain and simple not as strong as fiberglass done the right way. Useing cabosil to join a box is different from constructing a box with one layer of resin and a coat of cabosil. I have been working with working with fiberglass for over 15 years and trust me there is a time and place for shortcuts and I wouldn't recommend anyone use one in a subwoofer enclosure. ------------- Nik

Hey, is fiberglass repair cloth/mat the same thing as regular fiberglass mat. Do they just call it something different but in actuality it is the same thing?

So does using thte cabosil reduce the amount of layers you need to use mat on? Does cabosil make the interior of the box strong enough to prevent it from flexing? Help!!

That's what is used for. The problem is that 99% of the time is over used and used under the wrong circumstances. Just do it the right way. Like everything else in life, when you take a shortcut you end up with an inferior product. ------------- Nik
