I mixed in according to the label, sprayed on beautifully, except that it did not harden. It stayed tacky. Called sem directly, it turns out this bottle was past its shelf life.

I painted a plastic automotive bumper and used this flex additive. This is a vital chemical needed to ensure your paint doesn’t flake off your painted plastic parts. (You also need adhesion promoter as prep).I can’t remmber if I added this to the clear coat as well… honestly I am not a professional. I whacked out my bumper on a part of a truck tire on the highway, and I decieded to try this out. It has lasted me 6 months and looks pretty dang good, using some materials and tools off of Amazon.
