Rough night at the track? Just ask Jessica Power Racing.

After Can-Am last night, the #52 looked pretty beat up. But instead of hours of hammering panels, the crew laid their MD3 panels in the sun this morning and after about an hour the panels were good as new. โ˜€๏ธ๐Ÿ’ช

We always wish racers good, clean racing, but we love seeing teams like JPR experience the durability and ease of our High-Impact Plastic Body Panels.

Another sharp build from our friends at Royal Race Cars! ๐Ÿ‘‘ Love to see them sporting our new MD3 Plastic Scuff Plates!
