Try the black electrical tape instead, it won't show and you don't have to glue anything to your lock knob. Just unscrew the knob and take it out, then wrap the tape just once down the length of the knob, then when you screw it back in it won't show and it will stop the machine gun, or bouncing lock effect. It's a temporary fix of course, until you can afford the repair properly.
Greg Mieg you can, but idk if youbcan on all models, i have a 2006 c200 kompressor, watcged a video where you need to add a bit of tape and i didn't even need the tape, just unscrewed and put back and it's fixed now
