ahh gotcha. no, press n seal is different from regular food wrap. it has a light adhesive quality to it. it's also thicker and has a slight texture. so it's just one layer on the bottom and one on the top with the adhesive side against the pcb. the press n seal can be staticky, so I wore an anti-static bracelet and grounded it to be extra safe I didn't shock the board. you press those two layers together and make it as flush as you can get it. that creates a pretty tight seal. then you push the switches and stabilizers through.
