Cold rolled is about 15% stronger than hot rolled.

I find cold roll to be easier to get in my neck of the woods. None of my local suppliers carries hot roll in anything under 16ga and I've never found pickled and oiled.

I was told years ago that Hot Roll starts at 16 gage

In my application it would be used in 20 gauge for forming a door skin. From what I've read cold roll is easier to form anyway and if its 15% stronger then all the better. I have a Samuel steel supplier where I live thankfully.

Default tip

Avoid hot rolled if the mill scale will be an issue (like inside a fuel or liquid tank). Cold rolled is a little stiffer to work with... having said that, whatever you want to make from 16ga HR will be formable from 18ga/20 ga cold rolled so long as you are okay with welding thinner material.
Thin filler rod of steel then perhaps a top smear of silicone bronze to butter in all the pores and pockets....
if you are going with a top coat of wax or clear, there is nothing prettier than the look of steel with silicone bronze filler melted in there...
