Over the weekend while I was doing some maintenance and swapping out winter treads for some much appreciated summer tires I found a nice trick completely by accident. My magnetic hand held light rolled up against my floor jack before slifing it under the car and happened to make finding the center jack point on my Mazda much easier than fumbling around under the car. I left it attached while I moved around the car lifting it up from different points to get all four wheels and it was surprisingly nice.
Bonus tech tip - Hockey pucks with a groove cut into them make a great pinch weld saver.
