Fatboyz inc Posted May 4, 2012 Report Share Posted May 4, 2012 I have decided to sound proof and water proof and also rust proof al at the same time with a cheaper alternitive to Dynamat, you can find it a Bunnings or most hardwares it is called Weatherproof Tape... it is a bituman backed foil you can get different width rolls I went doe the one about a foot wide I needed two rolls at about $122.50 each compared to the Dynamat which would be around $5-600 to do exactly what I have done with this and it is the same thing (bituman backed foil) here are some pic's I also added an E.R.P.S. (Electronic Rust Prevention System) under the matting. tailpipez, KMsMK and heyhey 3 Link to comment Share on other sites More sharing options...
KMsMK Posted May 4, 2012 Report Share Posted May 4, 2012 It'd be good to see whether it does the trick long term. Good find Link to comment Share on other sites More sharing options...
Fatboyz inc Posted May 4, 2012 Author Report Share Posted May 4, 2012 Thanks KMsMK I have done this to a few cars now and it does work a treat nice and quiet I used rust converter on any surface rust that was on the floor and the bituman tape seals the floor just like a lot of people use bituman paint as a rust preventive in thier underbody spaying the tape is much thicker and you only cut the holes out you need in your floor so you then rely on good door seals if you get stuck in water to hold that out the car is much quieter then when I first got it and you get much better sound out of your stereo to because of the acoustic effect from the matting.

KMsMK Posted May 4, 2012 Report Share Posted May 4, 2012 Wish you told me this earlier. I used the brush on sound deadener, mongrel to use & it gets everywhere. I'll remember for next time. Fatboyz inc 1 Link to comment Share on other sites More sharing options...
Oldmate Posted May 6, 2012 Report Share Posted May 6, 2012 Yeah KM and the other prob with the brush on stuff is it never dries hard. Hate using that stuff. Link to comment Share on other sites More sharing options...
KMsMK Posted May 7, 2012 Report Share Posted May 7, 2012 I even managed to get it in my eye, stings really bad. tailpipez 1 Link to comment Share on other sites More sharing options...
Fatboyz inc Posted May 7, 2012 Author Report Share Posted May 7, 2012 If you use thinners with the brush on stuff it does set ..... Just a heads up also try using the brush on with the thinners in a degreasing gun and spray it on, then you get good spread and it drys well KMsMK 1 Link to comment Share on other sites More sharing options...
heyhey Posted May 9, 2012 Report Share Posted May 9, 2012 Great! I was about to purchase a dynamat alternative off eBay for almost the same money. However, how thick is this Bunnings stuff? Link to comment Share on other sites More sharing options...
Fatboyz inc Posted May 9, 2012 Author Report Share Posted May 9, 2012 The Bunnings stuff in about 1.5mm-2mm thick here are some pic's of the roll I just bought another roll to finish the car off it is $125 for a 10mroll @ 300mm wide and easy to use, cut and mould.

Sooty_10 Posted May 11, 2012 Report Share Posted May 11, 2012 Nice didnt know bunnings sells that stuff, already got some dynamat, but if I need some extra stuff I'll be ducking into the local bunnings for sure. How do you find the rust prevention system? Do you think it has any effect? Link to comment Share on other sites More sharing options...

Bizz Posted May 11, 2012 Report Share Posted May 11, 2012 It's aprox 2mm thick as I've been looking at it my self but they do do a fire wall sheet which is 10mm thick that I've worked out to be about the same price per m2. Link to comment Share on other sites More sharing options...

How do you find the rust prevention system? Do you think it has any effect? I had the E.R.P.S. brand on my old puslux, wich had a rust hole in the floor that I never repaired until I sold it which was 4years later and the hole never got any bigger and I am not that fussy when wash my 4b's so I believe in this system hence why I have put it in my shorty.

Sooty_10 Posted May 11, 2012 Report Share Posted May 11, 2012 How thick is the dynamat Sooty_10? Not 100%, but I can have a look at it tomorrow and maybe measure or see if I can find some info. But yeah pretty sure it is only a couple of mm thick. Got it off eBay about 6 months a go, for my cab chassis but never used it, was only about $240 for a bulk pack. Not sure how much of a wagon it would do, but if I run out I'll look at bunnings I reckon. Link to comment Share on other sites More sharing options...
heyhey Posted May 20, 2012 Report Share Posted May 20, 2012 Just picked up a roll, decent enough looking stuff (smells strong though). Just wondering, how nuts should I go with this stuff? I'm not going to knock out the original bitumen soundproofing on the floor pan. I plan on running a bead of body deadner that I have left over, around the existing bitumen mat, the run a another lot straight over the top. With the pilars behind the front doors, it you put the mat on the outside or inside? Roof? Firewall already has material matting. Link to comment Share on other sites More sharing options...
Arch Nemisis Posted May 20, 2012 Report Share Posted May 20, 2012 Just out of curiosity I'd look up what bitumen fumes do to you before slapping it on. Just so you make an informed decision. Link to comment Share on other sites More sharing options...
Glort Posted May 20, 2012 Report Share Posted May 20, 2012 For those interested in the bunnngs stuff, I'd try some trade places for it. Bunnings can be VERY exy on some things despite the advertising Hype. I buy a lot of plumbing fittings and get them from a Large Plumbing/ roofing Joint. On average gal fittings for isntance are about 1/3 the price they are at Bunnings. Copper and plastic is about the same, always less than half Bunnings price. I have found the same with electrical stuff from the wholesalers and timber especially. I imagine this stuff would be available from the bigger plumbing joints that do roofing materials or trade joints that cater to the stuffs primary use. It really pays to shop around for anything you need in Qty or is exy from bunnings. It's rare to find they are the cheapest and I'm yet to ever have a problem buying from a trade joint even specialist AC and gas Fitting stuff. For the firewall stuff, The Aircon trade use a foil backed closed cell foam for insulation and noise reduction purposes on ducting and big cooling tower type jobs. It comes in various widths but I usualy get it about 1200 wide. It's a good 10mm thick and would be good for the firewall or transmission tunnel where you also wanted to stop heat radiating through to the cabin. I forget the price but it's pretty cheap as it gets used by the mile. There is also a foil backed tape that is used with the foam for joining it and maintaining the same appearance. That isn't the cheapest stuff around but it sticks like chit to a blanket and takes the foil off the foam if you have to remove it 24 hrs later.

Ahhhh, "find a cheaper stocked item and we'll beat it by 10%". Seems like your doing yourself outta coin by going elsewhere. OH and BTW, you seem to like Bunnings enough in your sig. Personally I don't like Bunnings, they stock what they can get cheap usually meaning their products aren't neccearily the common sizes, types, etc. Pisses me off.

That's too thick and it will most likely absorb water (water vapour/liquid water). Link to comment Share on other sites More sharing options...

Nah, Tried that one. They then throw a clause in about it having to be a retail competitor and trade joints aren't their competitor. I told them, if you are loosing a sale to them, There is no question they are your competitor. Only reason I went back to them is because the other place had run out! :0) OH and BTW, you seem to like Bunnings enough in your sig. Sure do. It's one of the few shops I can spend an hour in and not be bored. They are a great convinence store. When you want a bunch of different things, its easier to pay a few bucks more and get it all in one go than chase round to 4 different places to get a couple of items from each. When you need a heap of stuff, they it's worthwhile going where you need to in order to get it at the right price. Personally I don't like Bunnings, they stock what they can get cheap usually meaning their products aren't neccearily the common sizes, types, etc. Pisses me off. What pisses me off with them is I find they have a limited and broken range. The other day I was there and wanted a 32>25mm PVC pressure pipe reducer. They had 20>15, 25>20 and 40>32 but no 32>25. I asked the guy if they had any stock that they didn't have out but he said they never carried them. I said why would you not have them when you have every other size? He just shrugged and said I don't know but I get asked for them a bit. Hmmm., That's too thick and it will most likely absorb water (water vapour/liquid water). Won't absorb water. It's treated not to so it dosent absorb condensation off pipes and duct work. Link to comment Share on other sites More sharing options...
