Our 1989 18ft outrage used to sit in saltwater. How do we remove the paint and make it look glossy new again? We have it in dry storage trailered.

You can find this topic has been discussed ad nauseum. You find it and other usefull information in past threads by going to the drop down menu about 2/3 of the way up the right side of the page and selecting to show topics from the past year or so.
But, the short answer to your question it to use "Peel-a-Way" wet sand if necessary and 2 step buff.

NB: Do not use methyl ketone based paint removers, they eat gelcoat, and say so right on the label.
I was just using PeelAway yesterday to prep for a KeelGuard.
What I found is that even after the PeelAway has been on 24hrs, there was still some left over paint, most of which came off with a scotch bright pad and water. But on my boat the prep done before painting was some pretty coarse scuffing with orbital sander and the paint still sat down in those scratches. It would take a *lot* of wet sanding and buffing to get rid of the prep scratches.
PeelAway is something that I've used a lot on houses. While it goes on vertical surfaces pretty well, doing the entire bottom of a boat with overhead horizontal surfaces would hard work.
I just gave up any idea of taking the paint of the bottom of the boat.

I used Peel Away today on 69 Nauset. I cut the paper into 1 foot strips and I liked the way it handles. I was surprised to get some pitting of gel coat hear and there. I left it on for 6 hours, but noticed that my bottom paint was quite soft after 2 hours. I plan to try more, but limit the time to 2 hours.

I know this is an old post, but I thought the information may be of use to someone.
Not finding Peel-Away available easily, I took a chance on something I had in my workshop: I chose a 6 x 8 inch area of my transom (next to the engine mounts) that has the blue bottom paint, and I sprayed on (ready?) Ace Hardware paint remover from a spray can. Let it work for about 5 minutes or so (worried about what would happen), and used a small piece of brass shim to scrape the area. Believe it or not, 95 percent of the bottom paint came off, and the gel coat was totally unaffected. I'm going to buff the balance off, and check the gel coat again to be sure, but it appears to work just fine.
