second skin luxury liner or normal MLV?? which
I thought those mass loaded vinyl might work
But isn't this second skin luxury liner pro just mass loaded vinyl ??
I also see this on eBay, which is a lot cheaper but I am not sure if it will be as effective as the luxury liner pro. the liner pro is 9 sq.ft. for 60 bucks and the one on eBay is 20 sq.ft. for 55 bucks??
which one should I get
