Three gouges and a scratch on an acoustic, any hope?

Think of them as the scars of war. They're the sort of thing that makes for amusing stories around the camp fire. "This here's from fighting off 300 Al Qaeda terrorists, with only ma geetar 'n a Kyser capo fer a knuckle-duster - 'n this is where ma baby boy pooped in the sound hole - 'n this i where ma dawg thought I wuz beein ay-tacked by ma geetar.............."

There is that option, but you could try steaming them up, sanding and sealing them.

Well, you know, most of the guitarists I know are rather proud of their "war wounds", myself included. They make for great stories (real or not). But, honestly, how many guitarists can say that their dog bit their guitar? (Turn the old "Uh, the dog ate my homework" into "Uh, my dog tried to eat my guitar!" I can tell you where every nick and ding and scratch has come from on all of my guitars. I think they develop a little more personality with each wound. One guitarist I know has a bridge on a classical acoustic that won't stay in position (and he's too lazy or cheap to have it fixed), so he put bright blue tape over it to hold it down. The tape's been there for at least 10 years. Good tape. And the thing stays in tune! He says it plays better with the blue tape, so he plans to leave it that way!
