FWIW, I bought 3/4" chrome moulding from t-molding.com, and used a locally bought 1.6mm cutter (1/16").
I didn't use any glue to hold it in, but had to hammer it in place. It's held in very firmly and takes a lot of effort to pull it out, and when it does come out it takes a little MDF with it.
5/64" would be a tiny bit easier to install, and also to remove I would guess.
