Thanks, we shall see.
I wasn't able to steam out all the marks. I think because it's more of a scratch or gouge and the wood is just gone. So I'm trying an old trick I learned on "This Old House".
I made some mahogany sawdust using scrap veneer and a little saw. Then dabbed a little glue into the scratch and sprinkled the sawdust on. Once the glue sets up, I'll sand it smooth.
