The one part non-skid I'm please to report held up nicely. I used Interlux Interdeck. I just wish I'd use cream or biege. The gray is hot in the sun. I going to use beige on the cockpit seats and floor. THen decide if I want to redo the deck.
I've had good luck with Epiphanes also.
If you like grey Interdeck, you may want to try mixing the white and the grey - it's not as dark, may be cooler and looks great.
