Changed my mind about using filler primer on plastic bumpers
I used to swear by using regular primer on plastic bumper repairs because it was cheaper and I figured it'd bond fine. Last month I was fixing a 2017 Civic front bumper at my shop in Toledo, sprayed my usual stuff, and three days later the customer came back with peeling paint all along the edge. I had to redo the whole job for free, lost like $150 in materials and a full Saturday. That mistake convinced me to finally try that adhesion promoter and flexible filler primer I'd been ignoring. The second time around the paint stuck hard, no lifting at all, even on the flex points. Now I won't touch a plastic bumper without that stuff, it's just not worth the risk. Has anyone else had a similar fail that made them switch up their process?
