This is a quick video case study of a "Stretched" dent repair in an akward spot. I just wanted to share a case study about the repair planning for this case. We use an acronym S.A.L.T.:
-Survey the dent shape and features and angles needed for vision
-Access discovery, how do we get to the backside of the dent
-Leverage, does the plan proved enough power to make controlled pushes
-Tool selection
About the dent:
Although smaller, this dent posed some challenges because of it's distance from factory access to the dent. To complicate things the dent itself was quite overstretched and creased.
Overstretched means that the metal (in this case High Strength Steel) was stretched past it's elastic limit during impact. The sheet metal thins and elongates but no longer returns to it's orginal length. Essentially the impact created more surface-area and doesn't fit into the former shape anymore! Something like a snapple bottle lid.
PDR is considered cold working so there are limitations but there are tricks to make the extra area occupy a smaller space.
I find impacts around impact beams often lead to over-stretched metal so repairing this type of damage needs careful consideration.
