ok so i just finished spraying a couple diecasts using the normal 1/4oz bottles thinned 3 parts paint to 2 parts thinner. color was great untill i got near the bottom of the bottle i had the thinned paint in. well when i got near the end the color lightened way up due to the flake settling i guess. and i always keep my paint moving when im spraying i never had this happen with metallics before... just seems like the metallic is not staying in suspension like it should. the color is still a great color but more silver then i wanted it..was perfect before the final coats i applied...anyone else have this issue? after this i dont think i will use the testors for painting my diecasts think i will do what ive been doing and emptying the paint out of spray cans and using it via air brush for better controll/spray pattern...like i said out of 7+ years of painting stuff i never had this happen! could it be the paint sat too long on the shelf or? hopefully some of you that are more experienced with testors can help me out... thanks in advance.
