[QUOTE="01vert, post: 7174306, member: 15873"] For the foam? no recommended, just get the low expanding. Home depot or Lowes has "great stuff" brand usually. If you plan on using the can more than once make sure you get a piece of wire to clean out the nozzle hose as it gets gunked up after use. Biggest thing I have ever seen is some trying to do too thick of a layer at once and the middle taking forever to dry and the foam expands all the while, ruining stuff. I have done about 1-2 ins thick at a time with about 24 hours drying time. Doing the beam should be easy, tape up the forward holes, add, then after the first treatment you could put the seat back and just add by removing the rear bottom and using the holes in the beam or making a couple small ones in the top/side. As for total mass under the seat, look for that same felt type material at Lowes when you buy the foam. WIth a couple inches of that stuff under your back seat should be as noise free as it is going to get. You could get 3M 77 spray adhesive at Walmart and layer this stuff together before adding it to make sure it packs well. Like I said before the felt will only add about $12 bucks maybe to the bill and will help (but is bulky). If you have it, the spare ensolite could be used on the rear trim panel in the trunk so the trunk doesnt act as an echo chamber towards the front of the car. [/QUOTE]
