Would you recommend it? Is it easy to use?
NO!
NO!
I found it to be some what of a pain to use.
It is very tacky and collects dirt.
No sound deadening.
If you are going to use it though I would buy the same exact product, but marketed for pipe wrap insulation, for cheaper.
A better product is Vinylbed. http://www.vinylbed.com/
I like the vinylbed. Good product. I’m using it on my layout and it works well. Reasonably priced.
