I have a 1989 Four Winns Sundowner. Aside from the hull being a dull grey/dark blue color. which I'm not crazy about, the paint/gel coat is looking a bit worn. Can the gel coat be painted? And if so, what would it typically cost for a 21' boat? Also, I'd like to change the color if possible.

Thanks.

Bob, To have someone do all the prep work and then paint the hull would be some serious $$, as you want it to be wet-sanded to 400 grit, and then sprayed. Alternatively, you can get a decent do it yourself paint job with the roll and tip method, using a high quality marine polyurethane paint. The paint is ~$40/qt. The sanding is all labor....

Re: Painting An Older Boat?

Exactly what Chris said, sand, prime, then roll and tip.
I would recommend 1 coat of primer and 2 coats of paint with a light wet 800+ grit sanding between coats.
A 21 footer would probably be about 1 1/2 qt primer and 3 qt of paint. Give or take.
I did an old 15ft trihull a few years ago and it came out pretty good.
It took less than 1 qt of primer and under 2qt of paint.

the only reason to paint a boat is because you dont like the color...

other than that ....the gellcoat can be re finished with some elbow grease and some time

Yup.. gel can be painted with or without primer ( I suggest primer always ! ).

Shop price would be about 2500-5k and up.. depending on primer/paint system/color/clearcoat and or wetsand and buff your final Mirror .. age of the boat .. condition of the boats surface ( brand new or 30 years old ) .. repairs needed .. and setup of the boat ( removal and replacement of ladders/hardware/decals/vinyl removal.. etc ). .. ( HULL ONLY .. NOT DECK ).

DIY depends on how well you want it to look. You can go Pro everything .. or save yourself some $ on materials and marksmanship ( we pros look for fly Shat and take extra measures to get rid of it .. We want Mirrors where some dont mind having imperfections ). You can/might be able to do it close to 25 % off material cost .. and 2-3 times longer ( at whatever your time is worth ). + Gratification on your part doing it yourself - the $ tools that you would need.

Add it all up .. sometimes a DIY is a bargain .. sometimes it sounds good but your expense is going to just the same ( more or less ) as having someone else do it.

I hope you get what im saying here ..

YD.

Thanks. Yup. That was all done with a roller, brush and Fire Red Interlux Brightside polyurethane in my FIL's barn. The paint job wasn't perfect, looked great at 10 ft, up close you could see some imperfections, but for a 1972 tri-hull she looked rather striking in red. Actually she still does. I sold her about 6 years ago but still occasionally see her on the river.

And back to the OP. Bob, I just remembered that Interlux has a very useful pdf on their website called Boat Painting Guide that I think you might find helpful.

Re: Painting An Older Boat?

my 22' was blue hull and off-white cap....repainted it bright yellow hull with white bottom and white cap.
alot of sanding and washing...
my hull got 2-3 coats of primer (since i was covering blue with yellow)
and i currently have 3 coats of yellow on her, will get a 4th coat when i'm done with the restore
i bought 4 qts of yellow...still have 1-1/2 qts left....went through about 3 qts of primer
roll-n-tip method.

you can see some of the sanding and prep work in my thread, and the first few coats of color going on

Thank you very much.
Working only on weekends, it took me about 4 months. I stripped all the hardware off, did some fiberglass repairs to the keel and bow, rewired all the electrical, painted and reassembled everything. I lucked out and the floor and transom were both solid, so I didn't have to rebuild those as well.

Re: Painting An Older Boat?

I painted my old boat with Pettit EasyPoxy on the hull and Valspar Tractor Implement Paint with Hardener on the top. I did use an HVLP spray gun but did some Roll n' Roll on the hull for the first coat. I worked well but I decided to buy a 60 gallon compressor and shoot the rest. Did it all for under $200 bucks. The EasyPoxy was $100. If I did it again, I'd do it ALL with the Valspar and it would cost under $100 bucks. My boat was only a 15 footer, so a 21 footer would prolly cost $150
