Well that's better

A big factor is UV protection. Makes big difference of a car sits in a garage or outside!
Rustoleum is super tough. Try DAing some off!!
Late Rustoleum I bouught was like $35 /gal. I can buy decent acrylic urethane with hardner for $275/gal. Yep you can spend !$1000/gal too!
But I still put in how many hours to get it ready for topcoat??
