I covered the ME method on the restore thread - but - I cannot stress this enough - ME is GREAT to remove Ball swirl - But please "take your time". I think I spend more time SLOWLY removing Ball Swirl than any other activity. Be observant - Even 5 extra seconds in one area is enough to scratch through the paint work.
Because you are "wearing out" the varnish (that's what they used as the CC in the old days), you need to keep the playfield clean - only use a little Novus.
VERY IMPORTANT - Wax this playfield often !
