[will it work]

thanks

[will it work]

also ive seen this liquid sound deadener and would this solve both of my problems? because it sound deadens by adding mass and its a gel so I can brush it on and make a seal so the water cant penetrate it and leak into my hatch area.

[will it work]

will it work or is it useless to use air duct insulator over the sound deadener matt ive already put down? ive seen people use it and it seems like it works. all help is useful. since im her I might as well ask, im leaking water into my hatch area and kind of know where its coming from. and it looks like its coming out of nowhere.so would it seal the leak from getting on the inside of my car if I use fiberglass resin? and coat the whole area just to be safe? if need more info just ask. thanks
