French polish is a great finish as it is light, thin, and EASILY repaired. But, as the OP has learned, French polish is a wood protective FINISH, NOT an impact protector. Obviously, the new finishes (UV cure polys, etc) are VERY tough and very hard (but also more difficult to repair). There's a reason that most high end classical guitars are French polished, and most high end steel strings AREN'T.

I would advise to take the guitar to someone who does FP regularly. The great Bob Benedetto said it best: "French polishers are born, not made"

And finally, the top looks to be Cedar or Redwood, both of which mar easily compared to the spruces.
