Hi all! I was wondering if any of you have painted tpu plastic. How did you prep it or did you and how clearcoat worked out? I painted and clearcoated one time phone cover that was kind of hard plastic but very thin and flexible. I was nervous about clearcoat but in the end just adding more flexible additive to my clear solved things out. Now Im thinkin could this same method work on tpu? Im still not sure about adhesion tho... Thanks for your wise words!
