Hey RR, if you color sand and polish the existing gel it will look great right after its done, however once it sees the sun it will return to its existing state, I know its not the popular answer but it would be a shame to do all the work, put it back together and wind up where you started. Re gel done right is expensive but will last you or the next guy a long time which adds value to your boat. If you go the Re gel route make sure they really know what they are doing. If you would like any help, please feel free to pm me.
