🧰 Required Tools & Equipment
- ✓ Bridge dent puller
- ✓ PDR hot glue gun
- ✓ Rubber mallet
- ✓ Plastic knockdown pen
- ✓ Heat gun or hair dryer
📦 Materials & Supplies
- ✓ PDR glue sticks (high-strength)
- ✓ 91% Isopropyl alcohol
- ✓ Microfiber towels
- ✓ Assorted plastic pulling tabs
⚠️ Safety Checkpoints & Warnings
- • Wear safety glasses to protect eyes in case a glue tab unexpectedly snaps off under tension.
- • Ensure panel temperature stays between 65°F and 85°F; never overheat paint with a heat gun above 120°F (49°C).
- • Verify the paint is original factory finish; repainted or cracked panels may peel under tension.
📋 Step-by-Step Guide (5 Steps)
Clean and Degrease the Dent Area
Spray 91% isopropyl alcohol generously over the dented area and wipe clean with a fresh microfiber towel. Remove all road grime, wax, and grease so the adhesive can bond securely. Inspect the paint surface closely under lighting to ensure there are no existing paint cracks.
- • Panel surface appears matte and clean with zero wax gloss or smudges under light reflection.
- • Leaving automotive wax on the paint, which causes the glue tab to release prematurely.
Heat the Panel and Glue the Pulling Tab
Gently warm the metal panel with a heat gun until warm to the touch (approx. 70-80°F). Select a plastic pulling tab slightly smaller than the dent crater, apply a thick bead of hot PDR glue to the tab face, and immediately press it firmly into the dead center of the dent. Hold light pressure for 10 seconds without squeezing all the glue out, then let it cure for 3 to 5 minutes.
- • Pulling tab sits centered in the dent with an even collar of cooled, cloudy glue visible around the rim.
- • Pushing the tab down so hard that all glue squeezes out to bare plastic.
Mount the Bridge Puller and Draw Out the Dent
Slide the bridge puller frame over the stem of the glued tab, resting the bridge feet firmly on the undamaged panel around the dent. Thread the hand knob onto the stem and rotate it clockwise slowly, turning half-a-turn every few seconds to gradually draw the metal upward. Continue turning until the dent pops up flush or slightly above the surrounding panel, or until the tab releases on its own.
- • The sunken dent bottom visibly lifts upward until the surrounding reflection straightens across the panel.
- • Cranking the tension knob too fast, ripping the tab off without moving the metal.
Release Glue and Remove the Tab
Spray 91% isopropyl alcohol directly around the edges of the glue pad remaining on the panel. Allow the alcohol to penetrate the bond for 30 seconds to break the surface adhesion. Peel the glue lump cleanly off the paint using your fingers or a plastic scraper.
- • Paint is completely bare and smooth with no sticky residue left on the metal.
- • Using metal screwdrivers or sharp scrapers to pry hardened glue off paint.
Knock Down High Crowns and Blend
Examine the repair from an angle using reflected light lines to check for high crowns or over-pulled spots. Place the rounded tip of the plastic knockdown pen precisely on any raised high spot. Tap the back of the pen lightly and rhythmically with a rubber mallet until the high spot sits perfectly level with the surrounding body line.
- • Reflected straight lines or strip lights travel across the repair area without bending, curving, or pinching.
- • Striking the knockdown tool with heavy force, creating new miniature dents.
