        The ZRC in cans is around $26-30 a quart, give or take for shipping
(so find a local source). If my math based on Scott's mail is right, that
makes the cost comparable to the spray cans at $6 on the basis of weight, not 
counting a small fudge factor for the propellant in the spray version. However
it takes me 2 1/2 spray cans to properly cover a section of 25G because I'm 
also painting a lot of newspaper behind the tower. I'm convinced it will be 
worse for both me and the surroundings when trying to spray paint sections 
that are erected. With the cans of paint and a mit (& plastic gloves) 
and brush I'm hoping to get 2-3 times the coverage of spray for this case.
It's the surface prep for erected sections that's the killer. I'd pay for 
spray cans of abrasive pad :-)
