I saw the Testers color shift at Hobby Lobby. It's a Rustoleum brand. Picked up the Rustoleum color shift at Lowes. Same price for a full size spray can as HL was getting for the hobby size. Said all that to say very disappointed. Sprayed over flat black and gloss black, heavy coat, light coat , virtually no shift of color. Guess that's why the paint on autos that really changes color is thousands of dollars per gallon.
