I used (PDR) Paintless Dent Repair / Hybrid Repair Method to eliminate or reduce 95% of bondo filler or the need to replace this quarter panel
Another repair I used (PDR) was a Paintless Dent Repair / Hybrid Repair Method to eliminate or reduce 95% of bondo filler or the need to replace this quarter panel. To replace this quarter panel, the manufacturer required the whole uniside and roof to be replaced!
