Favorite technique for removing rusted screws??

I have found these power extractors available at Sears to work very
well.

(copy and paste the address if it is too long)

I had to use them on a 6-32 countersunk screw in an inspection plate
under the leading egde. They have a carbide drill on one end (left
handed), with the proper size fluted extractor on the other end. For
small screws, the drill set on reverse usually does it. In fact, in
some instances, the left hand drill backs the screw out without using
the extractor (you do need a reversing drill).
Also, the advice to use replaceable tips in the screwdriver is a
good one. Even the best screwdriver will eventually get worn and be
susceptible "cam out". There are tips that have small spikes in the
groves that really grip well, especially when you also use a good paste
or compound too increase friction. They are much cheaper than having to
replace the whole screwdriver. A good oil penetrant like Aerokroil or
Mousemilk is good too. I've never tried the penetrant you used. Does it
work well?

round headed screws that attach aluminum sheet to steel tube.

Before attempting to remove these screws, I apply PB Blaster and let
them sit 24hrs. then I ensure the screwdriver slot is clean. Then
sometimes the screw backs out nicely; other times the screwdriver
slips out, beginning the process of rounding the head.

Does anyone have a series of steps they'd care to share on removing
rusted screws? - Mike
