Remember, it is the paint you are removing so the aluminum stripper
will work on the painted steel.
A few other points:
Most body shops will skim coat the entire car so small scratches are
not a problem at all, in fact if bondo is being used to fill in small
dings they usually leave a rougher finish to help with adhesion. If
the aluminum or steel is being straightened using traditional hammer
and dolly techniques it can be very rough because of the filing that
is done to find low and high spots in the process. Metal scrapers are
fine, just use them carefully.
Don't use a steel brush on the aluminum. I am told it can leave
embedded fragments in the aluminum that will rust. Always use a brash
wire brush on the aluminum.
