boat bottom help.

[hiVisions]

i have a 2005 16dlx carolina skiff that was used as a part time landing craft on rocky shoreline, a barge, and party craft. sat in salt water for 4 straight months. then given to me as a dept settlement. After removing the barnacles its left me with a very beat, chipped, and gouged gel coat under the water line.

Now i want to get the hull looking good again but am unsure if its worth spraying the outer hull with gel coat. I am also considering filling the voids then painting with imron or something else good.

if anyone could give me some pros and cons of these ideas or hopefully even betters ideas i would appreciate it.

Give it a good sanding with 40 grit, fill the voids with a mix of gelcoat and cabosil, sand with 80, 150, 320 grits and spray gelcoat with Duratec clear additive.
