scratches that will telegraph thru any new primer or paint you apply and
show on the surface of the new paint.
FWIW It certainly isn't a steel brush that I've used whenever I've done this,
but some softer (gold-coloured) metal - presumably brass. I'd expect the
average steel brush will make a mess of things, however.
I've not had a problem with scratches in such situations with the above, and
it's proved far quicker overall than using chemicals for paint removal. I keep
on toying with the idea of setting up some sort of blasting cabinet, more out
of curiosity than real need, but it's one of those projects that can wait
until I have more time (yeah, right :-) and somewhere more permanent to site
it. (I hear that things like baking powder work surprisingly well, and it'd
be interesting to do some experimentation)
