RE: Coverite 21 century cub paint doesn't match
I have a can of that Cub yellow Coverite paint. Tough paint, but it doesn't cover worth a damn. When you paint something, the color gets yellower, but stays translucent and you can still see what's under it. I use it on prop tips, it seems to resist chipping better than other paints.
You might want to try H-9 Ultracoat paint. It is acrylic enamel, fuelproof, and covers pretty well. Takes about three days to fully dry, though. I bought the bright yellow, trying to match yellow Solartex, and it was as close to exact as you can get without custom mixing.
