Once used plastidip whem making cyclocomputer sensor, dipped the breadboard with reed switch in it so it'd be weatherproof.

Also tried it on some bar ends (not an entire bar), it scrapes off easily and then looks ugly.


Try inner tubes for alternative bar coverings; however rather than cut them into strips and wrap as you would bar tape,
leave it in tube form and slip them over the bars for a seamless covering
choose a tube size of appropriatly tight diameter, compressed air is a must to make it go on....
