Default Painting my Potter SeaCraft

I have a Potter built SeaCraft Sceptre 238. Took me 19 months to find the boat. The boat is a little hungry especially in the condition of the hull finish. I am new to boating but very good with my hands (restored two corvettes when I was younger and I make and spray furniture). I am currently in the process of preparing the topsides for paint..removing all of the teak (to refinish) all of the cleats, windshield, etc. When I am done with the topsides I am going to take on the job of painting the hull.

In prepping the topsides I am just using a palm sander with a 220 to 320 grit just to rough and clean it up a little. I will then clean with denatured alcohol and fill any holes or cracks.

After i will lightly sand again, clean with den al again and prime.

I plan on spraying (with hvlp) Interlux Brightside finish and primer.

Should I apply two coats of Pre-Kote?

How many coats of Brightside do you recommend?

I know that I should sand lightly in between coats but what would you recommend as a process for dulling the shine a bit when finished? I have had people tell me that the sheen will die down on its own.

Next the Hull.

The Hull has two coats (poorly done) of red finish on it now.

I plan on spraying the hull with a hvlp as well. Haven't decided on Awlgrip, Perfection, Sterling, Etc yet.

Which would you recommend and why?

Have far do you think I should go on sanding the hull?

What do you think is the best filler to use for the deep scratches on the hull?

I know the post runs on a bit but I wanted to try and give as much info as I could think of.

I am keeping a photo log of all of my progress (and lack thereof). I will post when completed.

Thank you in advance for any help you can offer.

pics of the new hardtop from Atlantic Tower. I fit the top in advance of prepping the boat for finishes. It will be removed prior to spraying.

I would suggest you follow the paint mfg's recommendations on primers and paint. I don't know about other brands but Awlgrip has a flattening agent that can be added to the paint prior to spraying.

If there is paint on the boat already, you should check for adhesion. The Awlgrip application pamphlet has a good explanation of this.

Also, you might want to look into buying a DA sander. It will speed things up tremendously. 220-320 on a palm sander is not very aggressive and you may need to really get some material off before you prime.

3M Premium Marine filler is very good for filling imperfections above and below the waterline. It's fairly easy to sand (in the early stage of cure) and feathers well.

I have the exact same boat,same color(1974 23 potter Tsunami).Why not use the Perfection on the topsides as well? It's much more durable than the Brightside and it won't cost that much more.You can add a flattening agent to it as well.
I like the System three Quick Fair for filling nicks,dings, gouges, and screw holes.It's epoxy based and cures fast and sands easily.
If the topsides are gel coat you could spray them straight with perfection and no primer.

I sprayed mine with a two part urethane made by Epifanes,it's similar to other urethanes like Imron & Perfection.
My hull was the original red Seacraft gelcoat,and in good shape structurally, but it was faded.
I prepped it by first de-waxing it then a thorough sanding with 320 I sprayed two coats of interlux epoxy 2000 white primer followed by a sanding with 320 paper.
I then sprayed it with the two part Epifanes urethane.I shot two coats on it rather quickly the first day,let it cure overnight then sanded it again and finished up the next day with two more coats.
I'm a rookie sprayer but it came out nice,a few spots with some orange peel and one sag,so I had to sand and buff them out.

If yours has been painted you'll need to find out what was used so that you can make sure you use the proper primer,some are not compatible with certain paints.
I'm on the third year with this paint,and it still looks as good as the day it was done.If it was me I'd use a two part urethane like perfection on the entire boat,shines forever and wears like iron and is extremely fade resistant.
A few pictures of mine showing the finish.
