Super 90 is good but the prob with that is it is outlawed a lot of places due to the chemical makeup. The best way to spray if you can is to get a glue pot, it heats the glue and sticks better. Like Brandon said get some thin foam and lay it in there, if you want to do shapes and other things like that get some thicker foam and glue them on the thinner foam and then work the tweed around the shapes. Hope this helps.
