I bought 3 of these kits to do my truck. I still need 2 more kits. Easy to apply but, make sure you clean the areas where your applying or it will not work as good. Found out Mr. Clean and then rubbing alcohol works best. This stuff will cut ya so have a first aid kit handy. My cab is pretty solid and has a thud sound now. The back cab and floor still needs deading. I still have the 1/2" dynaliner to apply on top. My gas mileage has almost doubled since adding dynamat. Make sure to check out www.dynamat.com to get an idea. I covered pretty much every hole with strips and then layed my whole sheets. You'll see when you see the SPL section on doors. Mine is just as good without the dynaplate. Dynamat support said it would be like having the dynaplates installed. Course I'm building a compitition system for Iasca. I still need total of about $700.00 more dynamat, dynaliner, and another door kit. My doors outer skin, roof, king cab area took me about 8 hrs with small breaks, cleaning, applying and putting back together.
