28mm Warlord Legionnaires

Here we have a box of 30 Early Imperial Roman legion by Warlord. The figures are good, the shield transfers look nice but were a complete pain in the butt - they don't adhere well to the curved surface. I tried all the tricks - pva, gloss undercoat, Future, vinegar to help soften. Any hints? I can't seem to find and microset or microsol anywhere local, but maybe that is what I need.
