Axalta has been connected with JR Motorsports affiliate Hendrick Motorsports since 1992 and has a close business-to-business relationship with Hendrick Automotive Group, Rick Hendrick's privately held car dealership.
Along with the 15 XFINITY Series races with William Byron, Axalta previously announced a 13-race partnership with Dale Earnhardt Jr. on the No. 88 Hendrick Motorsports Chevrolet in the Monster Energy NASCAR Cup Series.
The announcement gives Byron sponsorship for 32 of 33 XFINITY Series this season with Liberty University filling 17 races as the primary sponsor. Axalta will serve as a prominent associate sponsor for all non-primary races.
