For in-store pickup only, Pep Boys continues to offer the 3M Paint Restoration System, model no. 39053, for $13.50. This $10 mail-in rebate cuts it to $3.50. That ties last month's mention as the best price we've seen. (It's also a current price low by $27, outside the price below.) This system removes oxidized paint and very light scratches in a 3-step application process. It's designed for use with an orbital sander or polisher. Rebate expires December 31.
A close price: Amazon offers it for $4.53 with free shipping, via a clippable coupon on the product page, Subscribe & Save, and this $10 mail-in rebate.
