TECH QUESTION: Esthetically Pleasing Material to Fill in Crack on Plastic Oboe? Please help.

I got a great deal on a doubling oboe for my wife for Christmas. I had bought her a pretty good vintage oboe a few years ago. But she became discouraged with it and asked me to sell it and "get it out of the house". So I obeyed as any well-seasoned husband would.

But this year, she's now asking for another oboe. So I went cheap and scored a nice modern Selmer Signet oboe off eBay at a super low price. The background on this horn is that it was bought by a tech for parts because the middle tenon socket was broken. But the tech though it was so new looking and nice that he decided to repair it.

I got it last night. And with a synthetic reed, I can play the oboe up and down with no trouble what so ever. It seems well regulated. The middle tenon joint is glued solidly together so I just now ordered a soprano sax gig bag to put it in and I'm returning the regular oboe case I ordered from Amazon. That's no problem. And I believe this inexpensive but great playing oboe will be just the thing for my wife to noodle around on and maybe even use in performance now and then.

My problem is that the repaired crack that is all the way around the center tenon socket is very visible and has left kind of a gash due to flaking. I'd like to try and fill this blemish in with some kind of epoxy, putty or other material that I can sand down and polish to match the shiny black plastic body. The crack is already professionally fix and seals. Filling in the blemish would only be for looks.

It you know what I could use to do this, please let me know. And thanks for you time. :bluewink:
