I cut the heads off a few fine thread bolts and wrapped them in tape and covered with release agent. They are used to align the holes only. You dont want to torque the action when bedding. Just push it down and wrap with masking tape. Electrical tape will stretch. I use a wrap of electrical then a wrap of masking tape to hold the action into the stock.

Have q tips and plastic knife handy for cleaning excess bedding compound.
Either remove the entire trigger assembly or coat the sear in release agent. Tape the box mag areas inside to help cleanup and trimming.
I only put two wraps of electrical tape on the tang.
