anyone used expanding foam in there cab ???

[coops714x4]

OK guys let me clear this up I am NOT using the spray foam that you get had the lumber yard or hardware store Im going to use a commercial CLOSED CELL, NON EXPANDING foam that is made for automotive use (READ MY LAST POST) right now I am researching products made by 3M, DOW,and DUPONT once I find the RIGHT product (THE ONE THAT I FEEL MOST COMFORTABLE WITH) I am going to experiment on a old cab first
One thing that concerns me right now is PREP these products seem to suggest that for these to work right prep is important and there is NO way to prep inside the roof panels. does anyone know what, if anything GM did to the metal that wasnt exposed did they use any kind of coating or inhibitor on them ?

Since I just Happen to work at Dow Automotive and We manufacture the foam used by the auto industry and marketed by other companies. I will get some tech data

And that's the problem with these trucks.
It doesn't matter how high a quality foam we get, we won't be able to get it to stick without getting in between to prep the surfaces properly.

Use Lizard Skin spray it on and then spray on it if ya want or cover it up.

Takes care of sound and vibrations as well, and drys in about an hour and 1/2.

And they make some that has ceramic mix for heat as well.

Planning on using it on my burban once I get ready to strip it out.

[coops714x4]

burb How are ya gonna get inside the roof ????

[68 IRON]

Coops, I gotcha! Ya prep is going to be important. GM probably dipped the cab or something. The only access I see is through the bed or cab light mounts. If it doesnt get sealed proper, the metal will probably sweat and hold the moisture... good luck and keep us posted.

[fastwillie 696969]

if you got a wife like i had ,ur glad to hear the noise

[68 IRON]

Tubbed, to my understanding Coops wants to spray inside the roof panels.

[Burb]

Well my headliner is gone on mine and metal is all I see all the way back to the rear a/c unit, and as for the area around the visor ... it is a liquid so it should cover well.

[68 IRON]

I didnt think of that...Subs have single skin and trucks dual panel. He wants to fill the void with closed cell, non expanding foam.

Wasn't thinking about a burb I forgot they only have single panel roof.. if i were doing a burb I would dynamat it and intstall a nice headliner

does anyone remember a rust product called OSPHO ? I used that stuff alot but havent seen it in awhile that would be a great metal prep for my project

[70STOVEBOLT]

Eastwood sells a product called Oxy-solv that you spray on bare metal and it forms a galvanized-like coating. I don't recall how much it is, but it comes in a spray bottle and you can paint over it, but you need to use a self-etching primer before paint. I used it on the floor of my truck probably 6-7 years ago when I discovered some scaly surface rust under the rubber floor mat. I haven't looked at it since I did it, I wonder how it looks now?

[coops714x4]

Ok guys here is a update after LOTS and LOTS of research I have come to the conclusion that NO ONE makes a closed cell non expanding foam that does not require alot of prep so with more research I have found a product that will work GREAT it is from a company called WURTH it is similar to lizard skin and line x but its ALOT cheaper its call stoneguard and is used by body shops and restoration pro's it can be sprayed.rolled brushed or just poured on or in
so were going to try it our plan is to turn the cab upside down and pour it in through the A and B pillars we are going to use a "snake cam" that is used by plummers to look in sewer lines to look in the cab and insure coverage once we have the roof coated we will spray it in the A and B pillars, interior light hole and cab light holes
Ill let ya know how it comes out

[72 tigger]

Sounds like a good plan

[68gmsee]

Wow, That's a lotta work to quiet it down. It would be interesting to note the difference by taking a decible meter reading before and after.

I think I'd almost try a foam padded type of head liner and sound deadening liner inside the doors and on the floor.

I am going to insulate the doors,floor,firewall,behind the gas tank, yes its a lot of effort BUT I plan on driving this truck the rest of my life

You do know that there's a cardboard like material between the inner and outer roof panels, right? Not sure how you're going to get it completely coated inside.

......uh-oh...

[iluvmy72]

I was tempted....but chose rubberized under coating instead....besides...where are you going to do it? You'd never get the full effect from it.

what do ya mean "where are you going to do it " im going to put it in between the roof and cab panels ? why wont I get the full effect ??? should get the same effect as using it anywhere else . all I can say to all of you "naysayers" is stand back and watch when I get done my cab will be as quiet as a MODERN truck

[60ratrod]

This should be interesting to see. My thoughts on this is it should quiet it down, help prevent rust if the prep is done right, and help insulate from heat better

but then how are you supposed to engage in sending the "3rd finger solute" to someone if you can't hear them yell at you first?

LOL...love this comment....do you have glass-packs???

[boundstaffpress]

Has anyone tried to use the insta-foam packing that Uline sells? It comes in a bag, and should not absorb moisture. It may trap moisture between the bag, and the sheetmetal, but maybe that could be taken care of with some spray-in prep.
