The fan-fold underlayment I'm using came with clear film on one side and silver foil on the other. I peeled off the foil (to prevent unwanted electrical problems with my switch point pivots, long wire nails which go all the way through the foam and into the plywood beneath it.) It wasn't very cooperative. The clear plastic was even less cooperative - I think it had been sprayed on.
After the first sheet, I didn't bother to peel the clear film. Latex caulk sticks to it just fine - but then, latex caulk sticks to just about everything!

The "skin" is actually a moisture barrier, since the foam is porous, humidity would be able to travel through it. We built our last portable layout with 2 layers of 1" foam, and removed the "skin" before laminating. It may not ever matter, but we decided on "better safe than sorry" route. Since you've already glued your cork, I wouldn't worry about it unless something happens. Worst case, simply shoot a little white glue under the problem area, and let it dry. Problem fixed.

Problems with cutting the foam with the covering on is why I removed it in the first place. Like I said, I don't see a problem with leaving it on. Time will tell I suppose.

I believe there are some different varieties of foam sold out there. The first time I had gone to buy my insulation foam, I noticed this material with the plastic cover as well.
The insulation foam that is normally used, like the Owens Corning variety, does not have any sort of plastic cover that needs to be removed.

The reflection of the glue bottle caught my eye. Should I be concered about future problems to come up if I didn't remove this plastic from the foam? Because I didn't :(. No one ever mentioned to me anything about this.

Ive never seen a plastic skin on foam insulation board (the pink and blue stuff). Is it on certain brands?
