Quick question...My t-bird was painted (Nationwide chain, starts with M and ends with O) 10 years before I bought it, and had 1 and 3/4 Gallons of paint in the trunk. Is this any good for touch up? Granted, its a metalic red (I've discovered red does not like sunlight), and 1 of the cans is still unopened (DuPont brand, not near it for more info). Any good, or dispose of it ? Thanks in advance.

Sincerely,
Matt
