Walmart offers the Turtle Wax Headlight Lens Restorer Kit, model no. T240KT, for $7.49. Opt for in-store pickup to dodge the $4.97 shipping charge. (Amazon offers the same with free shipping for Prime members.) That's the lowest total price we could find by $3. This kit includes three restoration pads of various grits, 4-oz. spray lubricant, 4-oz. lens clarifying compound, and a lens sealing wipe.
