FLAT OUT FLAT:
Flat Out Flat is a self-crosslinking water-based topcoat that mimics the lustrous look and feel of wax. The increased matting agents used to create "flat look" cause this wood finish to have less clarity, show fingerprints more and provide slightly less durability than High Performance. It is recommended for low-use projects other than kitchen cabinets and table tops.
