you may as well be discussing shipping your boat to the moon...I haven't heard of a boat being gelcoated in 20-30 years, I would question if you could find a vendor with the facilities, or interest, if you did the costs would kill the idea.
Start with the fact that to re-gelcoat a surface, your first must remove all the existing gelcoat, as thick gelcoat leads to spiderwebbing. Right there makes the cost of fairing and priming the same surface for paint look cheap.
