Not strange at all- bike theft is VERY common in my city, can't say I understand the mind of the bike thief-
But a bike that is going to be more work to clean up or re-paint- re-detail is going to be a deterent to a type of thief I think (semi-pro) The drug fix type will prob take anything they can nip.
I have partial primer\ paint and red electricians tape on mine, it's definitely one of a kind.
I HOPE this will make it seem not worth the effort.
A suggest from police is to etch onto parts- this CHOULD be done with a bit of artistry as to not look to bad- make a design and repeat it-like your logo.
