So if you plan on Cerakoting after the bed job, you will solve the problems of paste wax or any other release agent you use assuming you follow Cerakote's instructions by soaking in Acetone, preheating to boil out any residual oils and soaking again in Acetone after the blasting process. This will remove any residual release agent as well as any blast media and you'll be ready to apply the Cerakote to a clean, oil free surface. As for the bedding part, I carefully and lightly chamfer the edges of my bedding compound after curing. I also put a thin layer of tape on the forward surface and sides of the reoil lug, I use the high temp mylar tape that I use for camo jobs. If you use bedding studs in your receiver, try to find a snug fitting Delrin or nylon sleeve to put on the stud and into the pillar, this will help assure that you have things square as it cures. If you have a lathe its easy to make a tapered sleeve which is even better and assures that your studs are centered in the pillar. As for me, I prefer to Cerakote before bedding, you can still soak it in acetone to remove residual release agent. One last thing, I have come to be in the habit of removing the barrel from the receiver, if you don't it will be next to impossible to not have some oil bleed coming out the scope mount holes and around the recoil lug. This also allows me to get a nice even coat on the lug abutments and threads which make a difference when you want take it apart for some reason.
