Ok, I completely missed that step... chalking the entire inside of the suit. Thanks for the tip.All of the seam tape on the inside are tacky and will cause the suit to feel undersized as seams rub and catch against your underlayment.
ETA: here's the video from Seaskin.
Not a great option if concerned about potential health complications (go read up on talc/talcum/french chalk) even if you find some unscented product without asbestos in it. Guess I'll do this procedure in the garage and with a filter mask on.
