The NEW Blackplague Shrinky Box SB-4 is the tech’s choice for having a Shrinky box on-hand 24/7 for when you need it! This set has the most useful accessories and comes at the right price point that you can buy it before you need it. What does it do exactly? Well, when you have a super deep dent that starts to “oil can” or flop from high to low, the metal is stretched! WORKS ON STEEL AND ALUMINUM! It cannot be worked any further and be expected to come flat. That’s where the SB4 enters the game! Using its methods, you induce intense heat into micro areas and the expansion and cooling of those areas shrinks the metal, bringing the integrity back and allowing you to resume your dent work.
