My inclination would have been option 1 also.

As for option 3, if you first scrape the CA level with a single edge razor, and then use the strip-sanding method, you can avoid sand-throughs. I've banged on about these techniques in a number of threads here

Yes, I have used this razor/strip sanding technique with my STA-1HT after I put a small dent in the back. If I look carefully I can still see the CA area as there must be slight difference in optical density of the CA compared to Tru-oil! I have to look hard though.

Yeah, I imagine you're right about that. I've only done CA drop-fills on factory poly finishes (most likely polyester).
