Warping is caused by slight compression of the surface being blasted. =
This sets up uneven stresses that leads to the warping. We experience =
this at work all the time and use it to determine actual amount of time =
the part (titanium jet turbine blades) have been blasted, through the =
use of coupons called Almen Strips (thin strips of steel that are =
blasted at the same time as the blade, then are measured for warping).
If it were heat, the sheet metal would be discolored (blue).
The baking soda doesn't produce this effect because it isn't as =
effective (softer than the steel) and doesn't "peen" the surface as much =
as the harder abrasives. =20

What you are referring to here is warping due to heat. Flat panels =
will get surprisingly wavy if sand blasted due to heat. Then try a nice =
gloss black finish!
=20
Black beauty is available to me at the local hardware store in 80 # =
bags.
=20
Baking soda blasting will avoid the heat damage. To get this in bulk =
you need to find a good commercial blaster.
=20
And yes, coat it immediately. Even just a few hours will allow it to =
turn brown.

Are you planning on removing all the black undercoating crap too, =

In regards to the sand-blasting, I read somewhere (and will =

I don't know about POR 15; never used it. But, in my typical =
cheapass way, I have found and
effective, off-the-shelf solution: Rustoleum Rusty Metal Primer is =
absolutely the dogs bollocks
for sealing metal and preventing the spread of rust. I think it =
has fish oil or something (ever
see a rusty fish? Well there ya go).
I had bought a beater Rabbit for a girlfriend some decades ago, it =
had some surface and other
minor rust. I just wire brushed it off and put some RMP on it. On =
an exterior surface, that rust
didn't peek through for over two years, probably longer since I =
sorta dumped her and the car went
too, and I haven't seen hide nor hair of either one since (nor =
that $3000 she owes me...well,
that's another story).
I'm telling ya - when I get my MkI, out come the carpets and down =
goes RMP in any questionable
areas. Underneath too. Topcoat with other Rustoleum stuff iff'n =
you want.=20
My $0.02 says that common sense prevails...this is a cheap and =
very effective solution IMO.
