Does anyone have any advice about mixing products from different manufacturers?
If I am out of PPG slow hardener, any harm in using High Teck? Assuming they are the same mix ratios? I realize the isocyanate ratio needs to be correct for it to cure properly and mixing brands may leave some unbound. But does this cause a problem in the real world or just on the chemistry white board.
What about using a wet bed from House of Kolor and PPG Omni basecoat?
