So I told my insurance carrier that I had a better deal from another company and they miraculously found a better rate for me for the same coverage. However, when the policy came it said I needed proof that my VIN had been etched into all of my car windows. This wasn't the case, but I googled it and bought a kit for $25 on eBay. Simple process - they send you stickers with your VIN printed in it, you put them on your windows and then rub etching cream over the numbers. (It's a stencil, not a sticker I guess.) Worked like a charm. I'm thinking of trying to etch my own steel tools and maybe even a logo into metal to apply to my work. Just an FYI if you want to see if you can reduce your car insurance rates.
