Most of the poly plastic is OK. The trouble with the cheep drop cloths is that they are so light that they easilly rip. The Monokote backing is about 6 mill and a lot of the dorp cloth stuff is only 2mill.

A word of caution should be given. Keep the glue joints away pins. The CA will run to the closest pin and run down it and glue the plans to the board. Also, the plan covering is a one time shot. When the part comes off the board, pull the cover up also and throw it away and place a new cover on for the next part. Even if there isn't a pin sticking through the cover, the CA will find the old holes and glue you plan down at first chance.

By the way, I've tried parchment paper and it is OK for white glues. I've tried Cling Tite and It is OK. I picked up a 18" x 100ft roll of restrant grade plastic wrap and it was sort of OK. Wax paper is sort of OK, and as long as there isn't that much difference, pick up a couple rolls at the Dollar store and use it. Keeping the glue from flowing all over the place is more important than the type of plan covering.
