How to Repair a Cracked Bumper?
1 Answers
The repair method for a cracked bumper is as follows: 1. First, open the hood and remove the bumper. 2. Align the crack in the bumper and secure it with transparent tape to prevent deformation or misalignment during the operation. 3. Plug in the prepared soldering iron and flip the bumper over to inspect the crack from the inside. Wait for the soldering iron to heat up, then use it to melt and fix the crack inside the bumper. Operate along the direction of the crack. 4. Use the prepared PP welding rod and a plastic welding gun (hot air gun) to weld along the crack. 5. Remove the transparent tape used earlier on the bumper crack and also use the soldering iron to go over the crack again. Then, use 400-grit coarse sandpaper to smooth the areas treated with the soldering iron and those needing touch-up paint. Once smooth, apply putty and let it dry. 6. Use wet sandpaper, starting with coarse sandpaper and then switching to fine sandpaper to achieve a smooth finish. Rinse and dry with a clean cloth, then wait for it to dry completely before painting. 7. Before spraying, shake the spray paint well. Maintain a distance of about 20 centimeters from the surface to be painted. Avoid spraying directly to ensure even coverage. Maintain an angle and allow about 15 minutes between each coat, applying around five to six coats in total. 8. Let it dry for a few hours, then reattach the front panel of the bumper. This completes the crack repair.
