Alternatively, I use a nearly empty propane tank and give a quick 1/2 second blip of gas. Anything more or with a full tank will blow your fresh gasket seal.

My theory is that slight outward pressure will help seal the mag better and locate any areas that were too thin to begin with. I have had success with many gbb and gbbr mags with this method. I do not give a full gas charge until its fully cured. Minimum 24 hours in the summer or 2-4 days in cooler months.

Before any mag is inserted into a gun, I will give it a full fill and vent the entire mag inspecting for any chunks of gasket maker. If there's signs of residue, I will vent until there's none but that has only happened once or twice when I needed to rush a mag for someone.

Another thing I do is gas it up with the tank upright and adapter on top. Helps prevent liquid propane transfer.

YMMV.
