Since having my car fixed after a crash thanks to some pillock (a story for another time) my door handle sometimes stays stuck out once opened, getting frustrating when trying to close the door and have it bounce back because it won't catch lol. I'm assuming that if the door was sprayed it maybe excess paint? Any ideas on a fix?

Dont have a fix but mine does this time to time also.

Mine does it 2 now and then, I just spray it with GT85 then it's ok 4 a few months

Mine likewise -silicon ( as in Mr Sheen or WD40) usually sorts it out
