The Canadian Tire store only have 18 and 22 ga sheet metal. I think, once
I get some practice welding, I will splurge and buy a 4x8 sheet of 20ga
from Capital Iron ($60 cdn or so)
You're right, the 22ga is a bit thin, but it's easy to work. I now have a
piece of steel that *looks* a bit like a B-Post. I'll have to anneal it
soon so that I don't bash a hole in it, though.

Talked to my dad yesterday, we figured that paint would only be a few thou
thick. The surface is flat. I'd bet dollars to donuts that the metal is
20ga anyway...
I will be applying a lot of Galva Froid (or Spray Galv, or whatever I can
get) to the inside of my panels, so in the end they'll be almost as
"thick"-- and when I'm really rich I will do a proper BMIHT resto. Right
now my plan is to enjoy myself, and concours be damned ;-)
