What Adhesive is similar to that of 3M mounting pad?

What you want is generically called contact cement.  In addition to sheets, 3M has a popular type sold in spray cans.  Also, some stuff is sold in bottles or cans, and can be brushed on. 

Hi!

I don´t know how it´s in your area, but here in Finland 3M sells that "glue" (atleast that permanent one) in their shops. It´s not in cans or tubes, but it´s thin glue layer between two covering papers. Like that mounting pad, but without pad. Just glue. When I bought that it was about one meter wide roll and they cut as much I needed. Very sticky stuff

Check 3m web site and look what is your nearest reseller and ask do they have different kinds of that.

Hope this helps.
