I have an AW100 that has a dent on the front plate (?) and now the whole thing appears to be separating from the camera and I can see sand particles under there. Is it worth mailing off to get it repaired (can they even repair it? will it cost me more than a new one?). It still takes photos just fine, but I'm worried it's no long water proof, which is my main reason for owning it. Pictures are trying to show front plate coming away from the rest of the camera.
