I have a 38" x 50" laminated map that I want to mount. I plan on mounting it on 3/16" acid-free foamboard. The map is laminated on both sides. I was considering using either a vacuum press or 3M's Super 77. Any pro or cons about either method? I know that this topic was brought up earlier on a quite larger size map. Dry mounting, Super 77 or another way to mount this map - any information would be appreciated.
