Is marine grade interior paint really necessary? Considering the higher cost, I'm leaning towards a good low VOC enamel from Sherwin-Williams. Automotive grade primer and two topcoats.
In Don Casey's book, "This Old Boat" his recommendation for interior paint (Chapter Fourteen, "Brush and Roller", p. 321) is a good quality interior Alkyd enamel. "Marine" paint is unnecessary. The key to a good paint-job is a good preparation of the base including a good cleaning before applying paint. While it's not specified, you might find that a primer coat of "Kilz" is worth while particularly if you're dealing with an area that may be subject to mold. Note that you might be able to find a copy of Casey's book at your library or, an early edition, at a used book vendor. It is a very worthwhile addition to a boat's library.Is marine grade interior paint really necessary? Considering the higher cost, I'm leaning towards a good low VOC enamel from Sherwin-Williams.

Were the surfaces prepped properly before the original paint job?My previous boat was painted with non-marine enamel in the forepeak.
It was a hell with large flakes falling off.
I stripped it down as good as I could, and cleaned with acetone and painted it over with marine enamel. Years later when I sold the boat it still looked like new.
I think there is a difference.
To be honest, I have no idea, but my prep was not very thorrough. It was a dusty job, so I just did what I could with a brass-brush on my drill-machine.Were the surfaces prepped properly before the original paint job?
I am going to be painting the interior of my boat in the next few months. My bilge has never been painted. Should I even paint it? I would like it to be painted just to look good and clean- but am I creating a maintenance problem? Since I have do have some prop shaft seal leakage, my bilge is wet at the bottom- is it a problme to use "Bilge Coat" paint? Will it fail or should I use barrier coat as you suggest?Well I'm surprised no one clarified where you intend to use the paint? At least I didn't see it asked...
For bilges, where it would often be wet, I say spend the money and use a barrier coat product two part epoxy paint
For dry bilge areas, bilgecoat is good
For interior areas like cabin bulkheads and such I think you have some great recommendations, I would probably use something high gloss like you would use in a bath or kitchen with a good primer first, like Kiltz
You will run the risk of paint flakes clogging your bilge pumps.I am going to be painting the interior of my boat in the next few months. My bilge has never been painted. Should I even paint it?

In my non-professional opinion based on what others advised me in the passed, I would use a 2 part barrier coat type epoxy paint such as Pettit for the area of the bilge that is always wet. Because I have a keel stepped mast, I always have a about 8 oz of water in the lowest part of the bilge, therefore I used barrier coat. In lockers I used Bilgekote. All is holding up well after two years, no signs of flaking anywhere...but I prepped it well. Starting with a power wash where I could then several de-greasers applications followed by a good rinse, wiped down with mineral spirits IIRC, let dry with air circulation for several days, then apply the paints.I am going to be painting the interior of my boat in the next few months.
