om...
If an old aluminium hull (incl. many layers of paint...) isn't too
pretty anymore, should one sandblast it much like a steel hull? Or is
there some other procedure to make it smooth? Is the loss of hull
thickness negligible when sandblasting aluminium? And does anybody
know which primers/paints to apply, and how many layers? I'm assuming
it will be different from steel!

That will not make it smooth..

It will clean the aluminum and make a finish that collects dirt/oils
and will look horrible in a short time.

If you are going to ultimately paint it, sand blasting probably
wouldn't be a bad idea.
