Okay guys, Here`s what I have. MTK omni urethane piant, DT870 reducer & omni AU slow MH 168 hardner. I just wanted to check one last time right quick, that this is all compatable. Well I know the hardener is, but just checking on the DT870 reducer? also, its going to be around 70F, so am I okay to use the MH168 hardener & DT 870 reducer at that temp? Thanks AL
