if my doors are entirely carbon fibre or fiberglass, I would still require to use cld same way.?

[Harsh Kumar]

If my doors are nicely built with carbon fiber or fiberglass, there resonance/flex would be totally different from metal. Should I still use cld like I would on metal sheet, or something else between door n mlv.?

Sorry admims, if I posted in wrong category.. I am not sure about appropriate category for my question

[emperorjj1]

honestly not sure if the CLD would work the same on fiberglass/CF. Im thinking it would be better to try something like the spectrum spray. You should try e-mailing or calling SS to ask though

I would not use it on fiberglassed panels. It would not be needed. Deadener is mostly used on large flat areas to reduce the panels resonance. Fiberglass panels are usually curved and do not resonate in that way.

If anything, Closed cell foam would reduce the transfer of sound throgh the material. ie. road noise.

I bet if you have enough bass you could probaby crack those doors..I would say some liquid deadener would help out but I think cld would be a waste because its to stop resonance right? Fiberglass wouldnt have thag resonance but it would have alot of flex because its flexible..maybe try spectrum sludge and if it still doesnt get it done..more sludge lol
