What’s the best way to remove this broken oxidized clearcoat, but leave the camo paint underneath?

I have a live well on my 13ft Jon boat and a 1in threaded plug used to fit it. I think the threads have gotten bent along with the hole. I can just use an expansion boat plug, but it sticks out the bottom and hits the bunk on the trailer. The hole is 1in wide 1/4in thick.
