Clip this is a car forum. If you want to know about Resin Bonded Fiberglass (FRP) the internet would be a better to start. It would be seriously OT on this forum. Be warned it is messy and the learning curve if you are not handy can be stiff.

Don't mean to be antagonistic or anything, navin G, but fibreglass installation could very much pertain to automobiles, both as a sound insulator, a stiffener, as well as a rust inhibitor, and hence, would contribute greatly to the available knowlege on the forum.

Relevance to this thread too would not be in question, though another thread could be started. Although it could be a VFM damper.

At least in my humble opinion.

my earlier post - i want to build fibre glass stuff for my car but dont know a thing about it. it would be great if you or anyone could give details on how to build fibre glass step by step.

hi,

yes sir FG fabrication i asked about was for car use. i wanted to try out sub enclosure after that door panels etc etc. damping as well. i think it would be better if i start a new thread in DIY section. i might get into professional installation and it would be very helpful to hav experience before hand.

navinji i just asked you because you have experience on your side and you could better explain than googling. never mind there are tons of info on FG. but an indian can explain much better. you know the indian name for the materials(im assuming) used.

thanks

Elfie what you said is true. Fiberglas has variety of uses but in different forms.

As a insluator it is used in 1/2" or 3/4" or even 1-2" thick mat. I even suggest covering that mat with a fine cotton cloth to prevent the fibers from getting too loose.

As a stiffener it would need to be mixed with Resin. What I do is use woven fiberglas mat (not the unwoven kind) this mat has a weave that looks like a basket weave (if you know what i mean) and once I spread this mat over the area I want to sitffen I pour a resin I get from Dr. Beck's. I forget the exact model number of this resin but if you remind me again after tuesday I can find it and get back.

As a rust inhibhitor fiberglass is best uses as pre fab panels replacing exisitng steel sheet. Fiberglass does not rust! For a good finish one needs a mould and needs to sand and paint the panel after it is installed.

There's still one very minor rattle, havent been able to identify it yet..

forgot to take pics this time, will take pics and post when im doing the next door, thats hopefully on sunday.

The door's vibration is now neligible even at high volumes as compared to earlier, theres a big difference between both doors. This material has surely worked for me.. I'd say its total paisa vasool...

this is one happy DIYer signing off..

cheersss!
hey bro can you please the pics of the damping install? or atleast of the material used?in my car there had been cases of front door rattles due to the midbass components installed.as suggested by ice gods in the forum,i did remove tht plastic covers.it really did hell of difference but still at times when i increase the volume the rattles come back.also the bass from the woofer of the components is not tight.

Navin Ji can you make a new thread for the subwoofer under the front dash so that it will help those who are interested and we leave this thread dedicated for damping purpose only.....

Here is some VFM damping product which was nice and thick. Say about 7 mm thick and nicely composed. I compared it with a piece of Dynamat extreme lying in the corner of the same room where I saw this and found this to be better. Only downside was it is not self adhesive:











B&T can you shed more light on this product please?

7mm is way to thick. Ideally 2mm is enough.

I am not sure about the thickness. 7 mm is just an estimate. It could be less. Sorry for causing confusion.
