Sand' I feel like an idiot! Head for a hobby shop and order some Milliput Micro-fine putty. It's used for sculpting and filling places on plastic and other models. It dries almost ceramic like, but it can be easily sculpted and tooled while moist. Take a needle and snip off the end of the eye with some wire cutters (use eye protection!) and the resulting "U" becomes your applicator. With your other instruments of destruction, remove any excess from the ajoining grooves and try to even out the "crater". After it's dry, you can still work on it with very sharp needles or syringes, and further smooth it. It will leave a tiny white speck on the LP, but it will be much easier on your stylus. A FAR more radical method is the "baking soda and super glue" method. It's 100% success or 100% failure, and I very rarely attempt it on models anymore, unless I have to have the ultimate in strength. You can remove Milliput with acetone, which due to it's hazards, I don't reccomend people using on LP's, but this is the exception to the rule.
