Joel Blake Posted March 29, 2012 Share Posted March 29, 2012 OK so GPS is based on the Poli-Seal formula. I'd just like to know why GPS seems to out perform PS in the polish side of things by such a long shot? Something has to be different here! I've seen it quickly pull out some fairly good swirls with a single pass and finish down perfectly. IPA wiped to check if it filled and nothing.
