Got that right. Paint right over the rust, if you like. On my streeter,
I sand out the rust spots, rough up the bare clean steel with sandpaper
a bit (on the parts that are pitted, don't worry, it LIKES them that way)
and brush on clear POR-15 (it comes in clear, silver and black.) When I
get around to it, I rough up the POR-15 with some 600 grit sandpaper and
spray it with a touch-up can. I want the rust to go away and not come
back. I'm not persnickity about finish. Any car you intend to drive in
a Minnesota winter is an appliance anyway.

Other price: The solvent is reputed to be wildly toxic. I use it only
with a brush, only outside in the summer. If you plan on spraying it,
do so only if you are wearing a forced-fresh-air respirator. This stuff
is nothing to fool around with, but the results are worth the precautions.
You can't return it to the can after you have had some out, so take the
leftovers and paint your ramps, inside your bumpers, rusty steel wheels.
Don't bother brushing the rust off of them. Go back years later and find
them perfectly preserved. The finish in clear will still look wet. I
use a cheap foreign bristle brush and throw it away after it is hardened.
