Eventually getting round to it...
Was trying to find least expensive wire brish for angle grinder when I fell across polycarbide abrasive wheels.

"Ideal for use with angle grinders for automotive, engineering, DIY, marine and other applications for the removal of paint/rust and other flaking materials. Manufactured from nylon woven cord with a polyurethane coating impregnated with silicon carbide on a plastic backing disc."
This sounds as if it might be nicer to use. But I do still want to get the job done decently. Anyone got experience of both wire and this new-fangled polycarbide? Which is easier, better to use?
Really only got one garage door to do so product lifetime doesn't seem to be much of an issue.
