Here we have a fairly deep dent on the body line of a 750IL BMW. As you can see when you blow click on the diagram, you’ll notice the pinched lines above the center of the dent in photo #1. If you don’t release pressure off the crown, you are going to have a real hard time moving the dent.
The #2 photo you’ll notice the lines above the center dent are now straighter. Which indicates pressure has been removed. From here, we’ll work gradually push from top to bottom into the center.
As the we work the dent towards the center, the outside surrounding area will become tighter (Photo #3). We want to knock down the outside to help relieve pressure. This helps the flexibility in the paint so we don’t cause and cracking. Now it’s important you are very accurate pushing. A good idea would be to use some type of protection on the tip of your tool like tape or a plastic cover.
#4 photos shows a slight high and a low. You want to keep your dent always clean as possible before you work the center. (Some cases, you can work the center direct but in this case, the dent is too deep for this method) Make sure you switch sides between pushing and knocking down so you can keep your dent balanced and clean.
#5 This photo shows that we are close after repeating steps 3 & 4. Again we are always checking from one side to the other.
#6 The final step. Cross checking is important. Stand up and move your board in all directions to catch any curvature or fade that will indicate your repair. Clean and polish.
