We give a little insight about our big dent repair PDR training manual. These type of dents are very difficult to achieve and take a lot of patience. Even though we teach this technique, it takes much practice to gain perfection during and after the learning process.
This particular dent required pressure to be relieved below the outside edges (crowns). As we released the pressure, the crown would become weaker and more manageable. If we tried to knock down the edges before pressing, we would create "tap down" pits which can actually create the repair process become more messy. We did not use a glue pull method because at the time, it was not an option. Either way, the crown and trapped pressure would need physical behind the panel pushing.
We used about 2-3 tools to push the dent out. One in particular was the the soft tip from Ultra Dent Tools. Beware though, a soft tip is not the answer to all big dent repairs. It should only be used to start a big dent to release pressure and then change to smaller and more accurate tool tip. We explain in detail about this in our Basic PDR Line Board Manual.
Dents are becoming more bigger and complex because how thin the gage of the sheet metal has become. A simple door ding caused from the same impact 5 years ago will now create a silver dollar or bigger dent on todays vehicles. Metal becomes more stretched and deeper with lighter vehicle sheet metal.
Advanced PDR training has become more of a need to cater to the big dent repair market. Dents are not getting any smaller and big PDR dent repair is becoming a rapid growth to learn for all PDR technicians. There seems to be a shortage of door dings and a public demand for cost-effective big dent removals without visiting a collision center. PDR (Paintless Dent Removal) is slowing transitioning in to "PCR" (Paintless Collision Removal).
