Liquid Wrench offers Pro Penetrant and Lubricant powered by FlashSight Technology. The product features a built-in LED light located directly above the spray nozzle, enabling users to see where they spray to improve accuracy in low-light areas. Combined with a new product formulation that delivers the power of a penetrating oil able to cut through rust, grease and corrosion with a long-lasting lubricant that reduces friction and wear, the lubricant is a versatile tool for all trades.
