I want my bilge clean so I can actually see and also see leaks, etc. I have never had any cracks in the hull in the 23 boats I have owned so that isnít high on my priority list.

As to ventilation with Bilge Kote, I have never had any issues. I just paint quickly and then leave the boat for a couple of days. Never had any symptoms from the paint smell, I have had symptoms from other paints and solvents though.

When I repowered in 2006 I power washed the engine room, used a degreaser solution and after 2 weeks of drying time applied 2 coats of BilgeKote white. When I repowered again in 2018 I again did the same routine and applied 1 coat of BilgeKote white. It has held up very well over the years. I would not consider using some "oil based Rustolum paint" in the engine room, maybe in the cabin though.

I use Bilge Kote inside of cabinets and under seats where there was unfinished plywood or where the previous paint wasnít looking so good. I love it because it stands up so well to wear and tear. The difference in cost between good marine paint and other paint isnít even a rounding error in the overall cost of owning a boat.

I use Bilgecoat under the engines and epoxy bottom paint in the center bilge where water sometimes accumulates. Of course the center bilge was done after the boat was on the hard for an extended period (heated winter storage)... no trace of moisture.

OK well the OP's bilge is already painted so the bare-laminate horse has left the barn. I see what you are saying if a bilge has never been coated in any way.

My center bilge was painted. I scraped and sanded it to bare fiberglass, then repainted with several coats of epoxy bottom paint.

How would a fresh coat of paint do this?


The old lead paint was superb at stretching and flexing , todays paint not so much , but it might still cover stress cracks in the hull.

I recall using plain old dumb oil based paint from Home Depot in the bilges of my steel hull. Obviously degreased first really well, but no sanding or other prep. Worked great.

However, even with a respirator my head was spinning from the fumes from working in that confined space. If you go this route then rent a blower and put the SUCTION side into the far reach of the bilge. At another time, in the forward bilge, we had to burn tar out of the bilge and this blower method was 100% effective at keeping any tar smells out of the boat, which otherwise would have been permanent.

I used a PPG white epoxy paint on the Green boat. Prep was a through de greasing, sanding and vacuuming. I bought it at the local hardware store for a good price and verified with PPG that it was compatible with fiberglass.

Sold the boat in 2012 and it is still holding up well.

To me the latter would be visually cluttered and more likely dirty (harder to clean); so I'd be less likely to catch a problem.

Paint the bilge!

The cleaner and more uniform it is the easier to see problems.

Just a follow up. Power washed the bilge and degreased. Used the Rustolum oil based enamel. Flowed out and covered beautifully. I’m sore it’s gonna be just fine. Had hatched opened and a fan blowing. Oil based fumes are potent. Nice to use real paint instead of that water based stuff.

I was surprised to recently learn that two of the yards I frequent now use oil base Rustoleum on just about everything. They complain that the formulation of all the notable marine 1 and 2 part paints (Interlux, Petit, Epifanes, etc.) have changed and are simply not what they used to be. Have seen the results of the Rustoleum sprayed and rolled & tipped and the results were impressive.

I have been working my way through the bilge and engine room on my 1973 Hatteras, degreasing and painting with Rustoleum Professional oil based paint mixed with Valspar hardener with excellent results.

A little more costly but I like using Brightside one part polyurethane. Bright white, covers well, tough finish, resists everything, cleans easily. If you don't like the high gloss add some flattening agent.

Used Rustoleum successfully in the bilge 4 or 5 years ago. Has held up well.

Interlux Bilge coat - The white finish was high gloss - looked so good - painted the rest of the exposed hull. Virtually impervious to all spills.

My current new-to-me is getting a new coat this spring. It has not been done in a while. Do try to remember however, it is the bilge you are painting.

Just wondering what people have used in their bilge.

Why ask if you're going to push back on everyone's suggestion and do the one thing you wanted to do, that nobody agreed with???

I agree with the bilge coat. I used it on my 1980 Bertram and it stood up well. Prep is key (clean)
