(ET) ET Deck Painting & Rust Converting

[Steve Welch <swelch dejazzd com>]

So, to resurrect an old topic, I'm wondering what success y'all have had 
with coatings under the deck.  I have a deck that's basically straight and 
well worth using, but the underside has some decent rust pits and I'd like 
to convert / neutralize / eliminate the rust & coat it with something 
protective and durable.

I have used POR-15 on a previous deck and had the same experience as Chris 
T. did below.  I also looked into hot-dip galvanizing as suggested by 
Harry, but V&S wants $275 minimum and it has to completely clean & 
paint-free before they'll work with it.

Anybody have good experiences with other rust converters / neutralizers / 
coatings?  Inquiring minds want to know!

Thanks in advance,

Steve
