Have read a lot on it. I picked up some Xtreme Dynamat and some dynashield (in can) All for 55 bucs. I want to know which one I should put in my car first? Trying to save money and hopefully will be able to take one back. I am only doing the trunk like and the spoiler. Which one should i appy first?!

 

Dynashield does not work very well. I sprayed 2 can on the sides next to the rear seats but didn't feel any improvement. It's better to use the sheet.

 

I was gonna spray the dynashield in the spoiler brake light.

 

I stuffed my spoiler with polyfill. You can get it any craft store. It's what they stuff pillows with. I took a plastic coat hanger, cut off the bottom piece, the long section and used it to stuff the polyfill into the spoiler. It worked really well and my spoiler is as solid as a rock. If you tap it, it has a dead sound to it, not a hollow sound.

 

Fuken A MAN!!! Now that is a great idea. I know what I will be doing when I get my system back in my car!!

 

I did the same thing about 4 months ago. It does work well

 

Does it stop the spoiler from bouncing up and down w/ the subs on...my spoiler looks like it's gonna snap in half w/ my bass up. so far I dynomated the trunk lid and wrapped my spoiler wire inside the spoiler w/ felt tape. That helped a little but the spoiler still vibrates like a bastard!!
