FLAG Resin is a medium-bodied, non-blushing resin, which means you'll have no messy washdowns after applications. Resin is ideal for laminating vertical surfaces because of its increased sag resistance. Designed for use as an adhesive with any MAS non-blushing hardener. Clear finish means you get the structure and finish you want with just one product. Mix ratio is 2 to 1 by volume.
