Does help the paint adhere to plastic surfaces.
Worked well to help paid adhere to the plastic. Without this, paint would easily scratch off the surface. Sanding is critical as well as cleaning prior to painting, however this is another important step in prepping the surface.

Sprayed Atv plastic before bedlining. Seemed to work good
I sprayed my atv plastic with it before bedlining it. Bedliner stuck to the plastic real good.

So far so good!
Seems to help the paint adhere well. Only time will tell how long since the parts were plastic, metal and rubber. I even used it to help paint my wipers!
