Neither Photographer's Formulary nor Artcraft list PMT as available. The former used to offer it, but doesn't now. Other than commercial/industrial chemical supply houses, which typically only deal B2B, are you aware of any PMT sources today?
Moersch Finisher Blue contains it - and SE6 is designed to work well with Finisher Blue. I think 10ml/l of Finisher Blue in fairly strong working strength SE6 is supposed to render even MGWT chilly.
