Unless you live in a very large city and rely solely on public transportation (or your own two feet) to get you everywhere, there’s a good chance you’ll be buying a car sometime in the future. Unless you’re buying a brand-spanking new car, there are certain things you need to look at to make sure you aren’t getting a lemon. One thing that helps to know is if the car has its original paint job. If the vehicle is newer and has been repainted, it’s very likely that there has been some damage (and thus repair) to the car that you haven’t been told about. Here’s a handy little device that will let you know the status of the paint job.

This little keychain can quickly measure irregularities in the paint, which are tell-tale signs of a repair or fresh coat of paint. Knowing this information can help you to make a more informed decision when purchasing a used vehicle. You can also use the info to negotiate a lower purchase price. Not bad for a $20 gadget.
