  I have sanded down the inside of the roof and would like some advice in how to proceed.

  Should I paint the area with something like POR 15 and leave it at that .

  Or try to get hold of something like the original sound  deadner and glue it on to the bare steel then paint      primer/colour over it (as per original)

  I think it needs something there to stop the heat and noise so Im inclined to go with the second option .

  Does anybody know where I might buy some sound deadner or similar in Brisbane ?

Hey Brad
Make sure that whatever you get, that it is not thicker than the original deadener as you will have trouble with the headlining bows if it is.

dude your cars upside down :P :P i would paint it before you stuck anything to it.

Absolutely, seal it with some of the modern epoxy primers that are available now.  You could use a spray on deadener in stead of the board as it will be just as good.  Most sound deadener glue on stuff today is too thick as Alex mentioned.  You may remember seeing the hood bow indentations in the original board before you removed it?

I plan to go Ed Ho's way with dynamat extreme, this is what the car audio guys replace the factory stuff with and it cuts out more noise and heat than regular deadeners as well as improving the sound quality of the stereo, it also is known to have excellent bonding wich is important on the roof in the sun. you may notice this stuff on those foxtel shows as it is what is used in all the cars from people like chip foose.

did somebody say "dynamat"?

this stuff is great to deaden the panels.. dont confuse it with sound proofing because it's not.

this stuff stops your panels from drumming and at highway speeds makes the car alot less noisey.

so stick it your roof.

or floors or wherever you like.

apply it by "prepsoling" the area to remove wax or grease then apply it using a wall paper roller. I also made it super sticky by using a heat gun to make it .... stickier.

there is a warning on the packet that says "extremely sticky".. and it is.

some ppl use up to 3 layers but I feel that's unecessary.

your panels instead of going "clink" will now go "thud".

happy dynamatting

Cheers

Ed

this dynamat stuff seems great.   :o

Where is it available?  Does it come in various size sheets or is it a roll?
??? ???

its not cheap, you will need two bulk packs. the cheapest ive been able to find is on ebay @ $210 + $25 for 1 bulk pack, if you just want to do the roff and maybe around the speakers, 1 bulk pack is probably enough, car audio guys go crazy with it covering everything with 2 or 3 layers to get the most out of their sound system, as Ed said, it make the car sound very solid and the doors make a thid noise instead of the tinny clunk noise when you shut the doors and gives it a feel of a fancy luxury car wich could be good on long trips, best of all its a hidden modificatoin that doesnt affect the look of the car unless you line the boot area with it wich is common to do, you may need a wagon hoodlining in a van to do it but.
also I learned the hard way, dont leave any of the roof to be done when the car is back to the right way up.

dynamat have a website, not sure of the url but its probably something like www.dynamat.com

Thanks for the replies and info guys . I think I'll Por 15  the roof and go with the spray on urathane deadner .

Hey guys

just wondering what people have done to reduce road/engine noise???

At the moment my car is extremely loud if over 30mph and i want make it quieter so i can hear myself think and not get a headache from driving.

Cheers Ben

I used stone guard on the undercarriage and inside on the floor then used house carpet underlay then carpet....I wanted a quiet ride too.

i now have my two boxes of dynamat extreme ready to go on.
www.dynamat.com

Well i was going to use dynamat on the floors, then underlay and also replace the seals in all doors in the hope it would quieten it down enough???

On a brighter note got all parts for new motor so let the rebuild begin ;D

yeah, it might just need new oil.

Dynamat also have a new underlay out as well which is supposed to absorb noise better than the traditional style of underlay.

I've dynamatted, underlayed, replaced seals, stone guarded the floor.
I guess its reasonably "quiet", I can hear the stereo at least. 
The biggest source of noise ( i have) is wind noise around the window frames.  Best to align the doors as well as you can.

the only reaminging noise is the exhaust.. but i like that, the neighbours, missus and kid all hate the noise, but stuff 'em.... it's a V8  :D  ;D

Cheers

Ed

Hey Ben,
Don't use rubber underlay or the old style fibre underlay - use a woolen carpet underlay as it is very sound absorbent and being wool is not as susceptible to holding moisture.  Good luck with the rebuild :D keep us informed

regards
Weddo

Hey Bill

thanks for the tip, i'll keep it in mind  ;)

Have everything here ready bar gasket kit to build a hot 186 and also considering giving the paint a little freshen up and fit the new wheels ;D

Nice looking car,is it FC or FE.I see you have FE special trim on Gutter,under back window and boot lid.No strips under the tailights though?Nothing wrong with the wheels though apart from the HR caps....he he.Cheers,Jamie.

Hey Jamie

thanks for the kind words, its a 59 FC special that needs alot of TLC but has plenty of potential.

Needs even more TLC and has made me speed up plans as i blew a head gasket lastnight :'(

thanks for the tips on sound deadening... dont mention it.. :-\  :-\

LOL Sorry Ed i started to type a thanks to your reply and my laptop crashed :-\

I was going to use some spay on stone guard for underneath but figured i would try the underlay and tar on the inside first.

I realigned the drivers door (best i could) yesterday but they seem to be spaced out (with a spacer) so couldn't get it 100% fit.

Is it a common thing for the doors to be spaced and if so why???

Cheers Ben

i have that effect on computers . :D

There are lots of little tricks to align doors but im probably not the best to ask for little tips and tricks.

Some of the guys on here know a heap about how the factory did it.

Alfio or similar can probably provide tips from a professional panel panel guy perspective.

I just cheat to get the alignment as best i can...

Cheers

Ed

Im sure there are plenty of trade secrets when it comes to the alignment and hopefully someone is happy to share those with me :D

I never figured that the doors would be spaced from factory though can anyone shed any light on that for me???

Cheers Ben
