RE: Coverite 21 century cub paint doesn't match
There are 2 yellows. One is more of a chartruse. I used Cub yellow.
By the way, if you have some white primer around (any kind) try it on a scrap piece of anything. Then put a coat of your Coverite paint on it. Many primers work. And if it does, you will see the end result and know if the paint matches the covering.
