When wetting out if you have a corner of cloth that keeps popping up or a bubble that keeps appearing, covering the spot with a piece of poly which will hold the corner down or prevent air from sucking through the wet cloth. Kitchen wrap will stretch to shapes but wrinkles easily. 6 mil does not stretch to odd shapes but does not wrinkle on the flats. Either way fill coats and sanding covers tose small wrinkles easily and sure beats patching a bubble or a hole in the cloth.
