Hmm maybe I should get some fatmat for the doors since its cheaper and then some rammat for the trunk.
I am going to try fatmat out too since i am on a budget. Its cheap so if it does not work good o well.
Please don't.
I agree about the logo. Gets all over your hands. Looks like a blue logo, but comes off purple on your hands and is a bish to get off.
And that ought to tell you something. If you want to stop the owner of FatMat dead in his tracks, ask him how FatMat differs from Peel & Seal. As far as I can tell, the only difference is the logo. I have been involved in several debates with the guy on a few different forums and after many, many posts, that question makes him disappear.
If you are willing to use a much less effective product that carries serious risks of failure - either falling off or melting, why pay extra for somebody to stencil a label on something that is indistinguishable from the Peel & Seal you can buy at Lowe's for less? If you don't want to go to Lowe's, why not just buy P&S from the roofing supply company run by the guy who runs FatMat?
Looking at the value these products represent in terms of price per ft² really misses the point. You need to consider price per unit of mass AND the product's material properties. Butyl is always going to beat asphalt by a significant margin even when you are comparing products that weigh the same. Butyl is viscoelastic and asphalt is not. This means that much less butyl adhesive deadener will work better than much more asphalt, since all the asphalt can do is add mass. I've seen estimates from 2:1 - 4:1.
People like to ignore the functional differences and bring everything down to a question of reliability. The history of asphalt products failing in sound deadening applications has been very well documented. This goes well beyond "assumption". You will hear that asphalt failure is the result of poor installation technique but this is false. Asphalt will fall off immediately if you don't apply it correctly, but no matter how you install it, as soon it is applied you are in a race. The VOCs (toxic fumes) that keep asphalt flexible start outgassing. At the same time, the rubber compounds that give these products there limited heat tolerance start deteriorating. If you are lucky enough to have the VOCs completely evaporate before the stabilizers fail, you will be left with inert crud that will probably not fall off and can't melt. If the rubber goes first, you are left with material that will melt at very low temperatures.
A few years ago, I used to have fairly regular forum debates with Jacob from Sundown and Shon from ROE. Both advocated using Peel & Seal. Jacob in particular had an almost OCD level install technique. My point then, as now, was that if it doesn't fail, it will be better than nothing, but it will never be as good as a proper butyl/aluminum foil product. Both agreed with the performance aspect but insisted that the reliability issues can be controlled. Both have changed their positions after having the asphalt melt out after a couple of years. I only use these two examples because many of you will know them and can verify my version of things if you like. I've heard from dozens of others with the same story.
This fight can go on and on and since most failures occur after one, two or three years, many of the people who experience failures have moved on or are too embarrassed to report back. None of this really matters. When you consider performance per dollar spent, butyl/aluminum foil products will meet or beat the much cheaper per ft² asphalt every time. Being on a budget should lead you to buy less of a good product than more of a bad one.
Full coverage is the easiest way to apply vibration dampers but it is far from the most effective. The outside third of any panel will not benefit much from adding a sound deadener. Similarly, areas near bends in the sheet metal, welds, seat mounting points, etc. will yield little to no improvement. By using decent materials and applying them with a little thought, you can do a better job for less money and less work than you will achieve using asphalt with none of the downside.
