I Plastidip'd my brothers wing mirrors on his car using the rattle can as i was wanting to experiment.
Looked great and was really easy to reply - i put 4 light coats on with a heavier 5th coat.
However after a few days stone chips has sliced and punctured the coating and the white came back through.
I dont know if the professional stuff would be better where you use the airless gun, or if a primer is needed.
it did. I used there 300ml spray can. Not sure if the professional mix one would be any better. But still chipping after 2 days isnt very good.And even so it chiped? Hmm.. Not good!
