    Hey Guys,
    I received my Martin Jumbo Acoustic Kit today. I'm really excited to do my first acoustic build. I was about to to get started on it, but then I discovered that there were a lot of water stains on the mahogany sides. Is this normal? What do I do to get rid of them? sand them, etc... Should i return it and get a new kit? I've attached photos. Thanks!

    It's normal from the bending process. The wood has to be wet so it will bend. The stains will sand out.

    I doubt you'll be able to get a kit without the water marks.

    Alright, that's exactly what I wanted to hear. But how would I go about sanding it so that I don't mess it up?

    Also, what about those pencil marks? And the body is shaped like a jumbo guitar except for the two flaps on the outer edges where the body contours. I don't know what I'm supposed to do with those. What are their purpose? I uploaded a photo of one of them.

    The pencil marks are on the inside of the top and are wear the braces are glued.

    The two flaps with the holes are used by Martin during its assembly process to line up the top on the body. You don't need to use them. You cut them off when you trim the top down to size After you've glued it to the body.

    Thanks! How do I get rid of the water stains? What grade sand paper etc...
    Could somebody please give me some instruction? This is expensive wood and I really don't want to mess this up...
    I know where the braces go, I meant the large pencil mark across the side of one of the pieces. Should I sand that as well? Thanks!

    Here are some other resources you should check out before you do anything on the kit:

    Luthier's Forum - There is a section on building kit guitars.

    Kit Guitars Forum - John Hall from Blues Creek Guitars runs that one and is very helpful.

    Hoffman Guitars -- Charles Hoffman has a complete step-by-step description of the building process.

    Here's an article from the Kit Guitar Forum archives on the topic of burn marks and stains: Burn Marks and Stains

    There are a lot of resources available on the web. I recommend that you take some time and read up before you do anything to that kit.

    I hope this helps.
