I’m sure I’m not the only one that uses this stuff in a pinch or otherwise….how many of you have tossed a half can or more because it states must be used within 48 hours? Well Me for one…more than one can….so last time I used a can I had 3/4 left….so I stuck it with the other spray paint….I painted a gas tank today, and decided to test out their 48 hour theory….it turned out fabulous….that can had sat 2 weeks….so half can went back on the shelf…keep that damn expensive paint
