RE: Coverite 21 century cub paint doesn't match
If you want an EXACT match do the following:
Have a base coat of white or silver (yes that is correct, silver).
Take a sample of the color to a paint store and have them mix a quart of latex paint (cost is about $8 - $10 ).
After the parts are painted, let them "cure" for about 7 - 10 days, then clear coat them to protect them from the glow fuel.
Here is a basic "How To" for using latex paint.
Hope this helps.
