I like the matt finish, but I think if you polish it with T-Cut it'll come up shiny.
Never tried it on a UV-cured finish like the Smartwood has, but it certainly works on normal matt-finish Gibsons like the Faded models (or Fenders like the Highway Ones!).
But proceed with caution!!!
(Edit: If I remember right, the finish feels like it's pretty thin and has sunk into the grain somewhat? Might not give you a perfectly even, pretty gloss if you polish it)
