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
