The first time I sandblasted and painted Snoopy, I
put lots of coats of expensive epoxy on the outside, but had this same
exact thought about the inside. That surely won't get
wet, therefore cheap and ordinary paint should do! Well, when
Snoopy was in Florida the humidity was 100%, the temperature was something
ridiculous, and climbing in and out even splashed a little salt water inside.
With the combination of those three factors, when I was being towed out to a
dive site the inside rusted so fast I could actually see the rust move. I mean
that literally, you could see it popping up from under the paint, rather
like a paper towel that has been laid over a counter that's sprinkled with
water.
I still don't use as expensive a paint on the inside as the
outside, but one paint I've found is economical yet tough is a two
part epoxy for painting garage floors. It's very thick, giving really good
coverage, and resistant to abrasion. The downside is there aren't
any rust preventers in it because it's intended for concrete, so you
want to spray a base for metals underneath.

Hi All,
Im going to paint the inside of my battery pods today. As
theoretically, the insides should not get wet, i was thinking of using just a
normal metal paint like Hammerite or something. A straight forward paint
that you would use to paint outdoor railings and things with. Do you think
this will be ok or should i go for the "proper" 2 part epoxy marine
primer? Its just really expensive.
What do you think?
Thanks
James
