I am currently refinishing my wood, it is sooo easy even a stupid teenager like me can do it .....
Here is the link to the instructions I used.....
If the actual wood is damaged, I can't help you there, but these instructions will help you get the wood looking brand new! (Hopefully) I mean from the pictures, his turned out awesome!
