You'll need modeling clay, Acraglas Gel kit, a Dremel with a wood bit, masking tape, plenty of release agent, and a good dose of patience.
1st "hog" the area you're going to bed out. You're going to be using the Dremel with the wood cutter bit. Remember to keep the area you're going to bed shallow. You just want it deep enough to have a thick film of bedding. I strongly suggest you keep an "island" of wood around where the action screws go unless you're going to pillar bed it at the same time. Also remove a slight amount of wood from around the recoil lug area.
Next take the masking tape and tape the outside of the stock where you don't want excess bedding compound to go-it WILL stick to the finish of the stock.
Now is when you use the modeling clay to make "dams" to stop the bedding compound from going anywhere outside of the area you're bedding. You'll put the clay in places you don't want it to seep into like trigger area, mag well area, in front of the recoil lug, etc. It's important to make SURE you put clay in all areas the bedding compound will seep into.
This is the time to put release agent on ALL metal parts. In fact, put at least 3 coats on them. I like the spray release agent that Brownells sells.
You're finally ready to mix the compound. I use a touch of the color provided and mix (if you have Acraglas Gel like I recommend) it 50% resin and 50% hardener. Mix it thoroughly according to the directions or at least 1 minute. It'll start to be slightly warm when you're done. Remember it don't take much compound for what you're going to do. Apply the mixed compound to the areas you're bedding.
Seat the barreled action in the stock. LIGHTLY screw the action screws to just bottom out. You're not torquing the screws. Remember you applied release agent to all the screws and action? Don't be scared if some of the bedding oozes out on the sides of the stock-that's what the masking tape was for.
Wait about 1 hour and remove the excess bedding compound from the outside of the stock. Let it cure for several hours and remove the action from the stock. It'll be slightly hard to remove the screws and action. Remove all the clay. You can reuse the clay for your next bedding job. Now that it has fully hardened you may trim or grind the excess bedding.
