Help my car door opener (plastic painted handle ) is coming off. Is there a glue that I can use 2 put it on?
Basically it’s the kind where it’s plastic and in the door so you tuck your fingers under and pull outwards (towards you) and upwards to open the car. So is there a strong glue I can use before the whole thing peels off or do i have to get it professionally fixed???
Your best bet is to just replace it.
if you take the inner door panel off you will see how easy it is to swap out.
