after i radiused my rear fenders and cut up the inner wells i added the window seal spray can foam stuff from home depot and now no rattles or smoke in the cabin and when my door shuts it sounds like a freakin vault door....THUD i dont think it added any weight either maybe a pound or 2

Auto structural engineers are using automotive grade foam to improve torsional rigidity of the chassis with the added benefit of NVH reduction.
Used correctly foam offers benefits...however two part foam (catalyst ) is preferred in automotive production to promote curing in enclosed areas.
Closed cell foam is appropriate to prevent water absorbsion
Good job YODAONE. Way back when the car had the noisy BFG tires I went in to see what could be done about some of the road noise that would reverberate up through the wheel well arch. They don't have much to absorb there so this will remedy that. A local installer had some thin stuff that I applied around the arches and top deck which helped to some degree. I wasn't willing to pull the C pillar to place some in that area.
I've not felt the LS400's were all that quiet to some cars. I must hear or have different expectations of "quiet".

Carefull using Home Depot stuff
I have used the 2 part foam in the past for other car modifications and there is no way i could have filled the cut up inner fenders and it would have made a huge mess. not to mention it cost way more, i did both my rear fenders for $8.00 and was super easy to use.
I could be wrong but a/b foam also weighs considerably more than the expanding foam i used and i wasnt trying to strengthen anything or increase rigidity... may not matter to some people but i have a fully stripped LS with lexan windows and stuff.
its been in there for a few years now and no problems yet
