CA Glue crack repair colour burn-through

Hey, I've just had a go at repairing a cracked Epiphone Hummingbird and it all went well except burning through the colour of the finish when sanding it up to a gloss. Any ideas for patching this up?

I had another pass over the micromesh pads on some particularly rough spots and did manage to get to a good state. It would make sense that Rogue Grit has paid me a visit on some of the lower grit san…

Gibson Hummingbird pickguard?

Would I be right in guessing this guard is an aftermarket job?

Gibson Hummingbird hole repair

This is what happened when this guitar fell off a wall hook, and the head stock of the guitar hanging below it punched out a new sound hole. I don't consider the result a success. In fact I'm embarrassed that I wound up with an outline around the repair the screams "Here I am!". I've decided that instead of letting it be just a cringe worthy experience, I should have the humility to ask my peers for advice on how I could have done a bet…

Ah ok. That yellowish tape is kapton tape. Its normally used in electronics work, but I like it because is is impervious to solvents. Its also handy for taping on either side of an area I want to sand…
