Blue tape is basically my markings. I have a 97 E36 M3 and I am on another forum with a bunch of local guys who work on their BMW's too (saves alooooooot of money

) So we usually get together alot and help each other work on cars....well at the end of the project, I want to make for damn sure that all the tools I came with are coming home with me, so I mark them with blue tape (very easy to spot) That way, when we are putting away tools, all the guys know that blue tape tools are MINE. I also knew that I would be buying a starter set of tools from Craftsman, and maybe selling them in the future if I get nicer ones....so this way I don't have to etch, engrave, mark my tools which (in some people's eyes) brings down the re-sale value.
Anyone have any better ideas than my current system? I'm always open to ideas. It seems to have worked well so far, in fact I left a ratchet at my buddy's place, and he texted me to let me know I left it there, and he only knew that because of the blue tape. Seems to work......so far.
