Hi all:<br /><br />I have an 84 Bomber 15-ft fiberglass with a rather "used" look to the gel coat throughout the bottom 2/3 of the boat (the top 1/3 gel coat layer has maintained much of its gloss - kept under cover normally). I would like to restore to a condition as close to the top 1/3 as much as possible. Is this feasible? If so, any suggestions as to how to accomplish this (e.g. using oxalic acid, etc...).<br /><br />Thanks in advance.
