A toothpick can be used to apply the epoxy HOWEVER, I have found that dropping the mag on the floorplate or subjecting it to physical shock WILL break the bond. I believe this is due to Magpul using a Teflon additive in the PMAG polymer. I have since switched away from epoxy and now insert a stainless steel roll pin in the baseplate.

My preferred method is a roll pin in the baseplate. It's inconspicuous but robust.

Be careful with this. The polymer that PMAGs are made of WILL flex about 1-2mm and it only takes 2.5mm to slip the next round in. The ability to load on a closed bolt can result in your 10rd mag being able to accept an 11th (will not feed but the law is how many can it accept, not how many can it feed).
