That little amount, I'd just put some black fingernail polish around it, but that's me. Ode and Spuzz's way works too, if you have something to cut it with, without fucking it up. Believe me, it can be fucked up if you don't have the right tool to cut it.
Just order some Golfworks 24 hr epoxy. I can get it @ Golf Galaxy for $6.95 + tax. If you want, I'll get some and ship it to you. Still cheaper than the stuff you listed. If you order it from Golfworks, still cheaper.
