(ET) How much POR-15?

["David Roden" <etpost drmm net>]

I'm going  to try this stuff (POR-15) on the underside of the 36" mower 
deck 
for my New Idea rider.  It now has spray-on appliance "epoxy" enamel on it 
(applied a couple of years ago) and the rust is bubbling back through.

I plan to have the underside sandblasted to remove the old paint and rust. 
 
>From what I read on the POR-15 website it appears that all I have to do 
>is 
wipe off the dust and brush the POR-15 onto the bare metal.  (Right?)

I don't plan to paint the top of the deck.  It's scratched up and it's not 
pretty but I don't really care; that's just appearance.  This is supposed 
to 
be a working machine, not one that I take to shows.

What I want to know is, how much POR-15 should I order?  There are some 
pretty vorpal pits in the steel, so I'll want to apply 2 or 3 coats, and 
the 
paint will be doing some filling, so the stated coverage of 12 ft^2 per 
4oz 
is probably overly optimistic.

The $25 pint is a much better deal per unit of measure than the six-pack 
of 
tiny 4oz cans - but if I buy a pint, will I use it all?  It appears that 
shelf life once the can is opened is pretty poor.

Also, how does POR-15 stand up under decks?  Should I consider a 2-part 
topcoat for durability?

I'll appreciate guidance from those who have experience with the stuff.  

If you'd rather email me privately than post on the list, please don't 
reply 
to the address above, as it won't reach me.  Instead form my email address 
by concatenating the mailname "evadm", the second level domain "drmm", and 
the top level domain (TLD) "net", using the proper punctuation.  (Example 
of 
how to assemble: mailname second-level-domain tld)  Sorry to do this but 
the 
list is archived with no address obfuscation, and I don't want the 
spambots 
to harvest that address, as they have every other address I've used on 
this 
list.

Thanks again.
