SEM Flexible Primer Surfacer Aerosol Gray is rated 3.6667 out of 5 by 3.
Rated 5 out of 5 by from Works great on plastic Bought this to prime plastic catchers masks. First primer I've found that holds well. Haven't seen how it holds up to a baseball season yet. Builds very nicely folling the instructions on the can. I scuffed the surface, used SEM plastic prep and then this primer. 3 light coats and I have full coverage and good build. was able to scuff the surface and paint. Very happy with it so far.

Rated 2 out of 5 by from unhappy Bought 5 cans. 2 of the five were "spitters". Unusable. When I tried spraying with them they would spit solid drops of product. Hoping Eastwood will take them back. Other than the faulty cans this product works well with flexible materials such as bumper covers.
