I have a 92' Ranger that has some moderate to heavy oxidation. The gel coat is still in good shape and has never been touched with sand paper and the flake has not come through the coating. What process do I begin to tackling this situation. Id like to have my boat shining again. Im doubtful that all Ill need to do is buff. So im willing to take the sand paper to it. Just not sure how to begin and end.
