For possible fluid leaks I have just used puppy pads. They dont work well if you are rolling a creeper over them as they tend to bunch up under the wheels but are fine if you are only laying on them. They will also blow away if its windy unless weighted down with rocks or something (tape them together for needed size and weigh down the corners)I am looking for suggestions to protect the tarmac driveway when working on the car. There's a (good) chance rust, oil, brake fluid will leak. Something like an oversized shoe tray would be awesome. Any sugestions?
