Gaffney, S.C. (March 15, 2018) – Auto Club Speedway (ACS) is uncharted territory for rookie driver, Matt Mills. Mills will be making his first start at the Fontana, C.A., track in this Saturday’s NASCAR Xfinity Series California 300.

Flex Glue, the newest addition to the Flex Seal Family of Products, will be on board Mills’ No. 15 JD Motorsports with Gary Keller Chevrolet Camaro this weekend.

“Auto Club Speedway will definitely be a challenge, but I’m confident that my teammates will give me good advice,” said Mills. “The car I’ll be racing this weekend is the same one I had in Vegas, and that was the best race I’ve had so far. All in all, I’m very excited to make my first laps around ACS this weekend.”

NASCAR Xfinity Series practice is scheduled for 12:35 p.m. and 2:35 p.m. (PST) Friday. Qualifying will start at 10:35 a.m. (PST) on Saturday, and the California 300 will get the green flag at 2:00 p.m. (5:00 p.m. ET) on FS1.
