Hi Bruce,
Agitate, scrape and vacuum as much loose stuff &
scale as practical and then treat metal surfaces with Ospho.
www.ospho.com
I've been using the stuff for decades (found out
about it in Hawaii, on a cruise). It's magic,
basically a dilute form of phosphoric acid with
modifiers so it flows nicely. You can paint it
afterward with Rustorleum if you feel like it, or
just do a "top-up" treatment each year.
Handyman tip: applied to rust stains with a
scotch-brite pad, easy to rid of the stains on
anything (copious amounts of water to protect surrounding area).

My older CruisAir pans are metal  with a side
drain. You could try Rustoleum primer and a
finish coat or that crazy rubber stuff.

I have a CruisAir A/C. The condensate pan is
plastic or composite but even it drains from the
side. I think they design them that way
because more often than not, the pan sits on a flat surface.
Anyway, I almost cringe to suggest this but what
about some of that crazy rubber stuff they
advertise on TV? The commercial where they
make a boat out of screen and coat it with the rubbery stuff?

Hello all,
We have a 1994 C&C 37/40+ with an Adler/Barbour
A/C unit. The drain pan is the issue. When
we bought the boat, the surveyor noticed the
rusty pan, and suggested cleaning out the rust.
In addition, the drain for the pan for some
reason is in the side of the unit rather than in
the bottom. The hose then attaches, runs a
couple inches and goes through a hole and down
to the through-hull. Why the pan was not made
out of Aluminum, Stainless or HDPE is beyond
me! Instead, it is painted mild steel. Ugh...
That said, the paint is flaking off, and is
somewhat rubbery, and therefore clogging the
drain. My questions are as follows:
The unit seems relatively difficult to get out,
and access to the far side of the pan is
virtually impossible. Is there a cure for the
rust & paint peeling that does not involve
removing the unit? Also, have any of you
revised the drain so that it drains down, rather
than through the side of the pan? Have any of
you replaced the pan, and how big a deal was it?
Thanks for all your help,
Â
