Kung slight bingkong lang, alam ko NH Miller, may machine press. Word of caution, though, madaming horror stories (as in sandamakmak) about Miller in this forum.
Since I'm a cheapskate, I had my mags pressed (using the "init" method) sa RM 4 Life, Regalado Avenue, Fairview, QC. P450 lang kasi (stock mags ng 97 Accord VTi-S). Sumisirit kasi hangin, kahit very slight lang yung deformity, kaya I had it repaired. Kung pina-machine press ko yun, baka P1,500 ang singil.
try autobahn along west ave. katapat halos ng miller yan. pero they dont unmount rims from the tires, so you'll have to bring it to them unmounted already.
