As a painting contractor who paints kitchen cabinets frequently, I’ve used C2 maybe 40-60 times. I’ve always liked the self leveling, and washability.
Unfortunately, when painting straight white C2 cabinet & Trim Paint, the coverage becomes a problem for painting contractors. Applying 3-4 coats takes a lot more time, and slows the over all cure time.
On the plus side, C2 has a hardener that can be applied to paint to give it an even stronger finish. The hardener stops oils from fingers that smudge kitchen cabinets.
Over an extended period of time these oils that sit on the kitchen cabinets for an extended period of time can cause the paint to scratch off. No other cabinet grade paint has a hardening additive.
