Adhesion promoters haven't worked for me, either. Black hinge covers, windlace and the area around the seat lock handle knob on the bucket seat back panel all seem to shed their paint, requiring constant touch-ups. Those with black interiors don't know how easy they got it !!
"Paint to match", my @ss!!
There...I got it out. Thanks for letting me vent.
p.s. I noticed in the newest NPD catalogue that they now have white bucket seat back panels. Hopefully, the hinge covers and windlace will follow soon.
