This is about repairing the finish on a guitar but, there's a few neat ideas for anyone who needs to repair small defects. Especially, his razor blade scraper trick.

Finish Repair

Now that's the bee's knees!

Polyester is a different animal.  I've only seen it on pianos, though not all pianos.

 

The classic repair for furniture is a "burn in" repair where a resin stick is melted, dropped in, leveled and smoothed.  You need to worry about color, transparency, grain, texture and sheen.   That's why they pay us the big bucks.  I had a guy watching me once and said he'd never caught the hang of it.   I told him that it takes a few hundred times of practice (and even then every once in a while things throw you).   He said he must be a slow learner because he'd been trying for 10 years and still couldn't do it.
