The third-generation racer has picked up four points-paying race wins thus far in 2021, and three out of four at the Roadways Tasmanian Ten Thousand which saw him score a $10,000 cash prize.
As the season moves through its halfway point in Sydney, Seton's Trans Am Mustang has now attracted backing from Turtle Wax.
The car care brand takes up positions on the doors and front bar of the #1 Harris Racing entry, which continues to be supported also by oil giant Castrol.
The 22-year-old also works for MSR in its mechanical department, and tested one of the ZB Commodores which the team fields in the Repco Supercars Championship at The Bend last week.
The Trans Ams will qualify tonight under lights at SMP before two races on Saturday and one on Sunday.
