Despite it being a blatant advertisement, we couldn't help but show you this video of a guy hitting an Acura NSX with a shovel at full swing. Three times. The amazing part? It doesn't leave a mark because of a product called "DoorPal", which somehow protects the aluminum-bodied NSX from any harm. The company's web site doesn't list exactly what the DoorPal is made from, but it looks like a heavy duty version of those floaty toys you lay on while sipping a drink at the pool. We're not about to see if one of those works just as well, but you're welcome to try. Check out the NSX narrowly escaping a beat-down after the jump.
