both, mostly before..I like epoxy under my arse grommet,,I hate epoxy in my screws on pikies and surfsters,,I like the epoxy under the screws.. I hate epoxy on my lips and I shake like Keith Richards ,, Sometimes I epoxy my lips in after,, putting some epoxy underneath and sliding home . Alot of times I drill a 3/16 hole up front for nose grommet and an 1/8 inch in the arse so arse grommet fits tight and don't slide around a giant 3/16 hole.. my personal prefferences to date .. may change when i make a thousand more plugs ..
