DIY Bumper Crack Repair
Here's how to repair a crack in a plastic bumper. Cracked bumpers are common on many vehicles that frequent shopping malls drive on rural roads. Often times a replacement is not warranted due to high cost or low quality replacements. This video demonstrates how you can fix your cracked bumper by yourself at home, with supplies you can get from any auto-parts store. First, a V-groove is grinded into the back of the crack to increase the surface area for the epoxy adhesion. The crack is then sanded and cleaned. The top of the crack was secured with a clamp and the front of the crack was held together with tape. JB-Weld Plastic Bonder was then used to fill in the crack from behind. Drywall tape was used as a reinforcement and the setup was allowed to cure overnight. After the 2-part epoxy is dried, it will be rock hard. From the front, the crack should now be much less visible if it was aligned properly. Sand the front of the bumper around the damaged area. Use plastic auto-body filler to fill in the cracks, and progressively sand the filler off before applying primer. Use some rubbing alcohol, paint thinner or acetone to clean the surface before applying primer. The primer was then wetsanded before paint was applied. The paint was ordered in a spray can from CarQuest and mixed according to the paint code. The color match is very close, just slightly darker due to the 12 year old oxidized paint, and there is a decent pearl that shines back in the sunlight. Two thin layers are applied then allowed to dry for a few hours before handling. The bumper can then be replaced on the vehicle and fasteners reattached. Wait a few days for the paint to fully cure before applying polish and wax. Now stand back and enjoy your repaired bumper. The whole process shouldn't take more than a day if you factor in drying time. This video is an excellent tutorial to follow: https://www.youtube.com/watch?v=EqzJ2VMrgQ0





Fix Plastic Bumper Damage: Complete Kit
http://scratchwizard.net TRANSCRIPTION: In this video you will learn how to take bumper damage like this, and make it look like this, using the BumperWizard bumper repair kit. Apply masking tape to adjacent panels and plastic trim that could be sprayed with paint. Wrap your scuff pad in coarse sandpaper, and sand the bumper with firm pressure. Wipe away dust and clean the entire panel with wax and grease remover. You might find that some of the scratches won't sand out. You'll want to apply a thin layer of scratch-filling putty with the supplied plastic spreader. Again, wrap sandpaper around your grey scuff pad and sand with firm pressure. Sometimes you'll find that a second application of putty is needed. Next take your scuff pad, and scuff a minimum of ten inches in every direction from the repair area. This is very important, and ensures that the paint you apply is going to permanently stick and be durable over time. Be sure to apply newspaper or butcher paper over any areas that could possibly sprayed with overspray from your paint cans. Now shake your primer can for about 60 seconds and apply one thin layer. Now apply a heavy layer of primer, until you've just about covered all the bare black plastic exposed after you sanded out the scratches in your paint. With light pressure, sand your primer until it feels smooth, using your fine-grit sandpaper. Shake your jar of paint for about 30 seconds and insert the spray unit. Now apply a thin layer of your paint. I found that the paint was going with some bumps, and I could see some cloudiness and some cat scratches in there. I didn't quite have a flat surface to work with, it was a little premature spraying the paint on there. I waited 5 minutes for this to harden, and I took out my fine sandpaper and knocked down any scratches or any roughness that was in the surface. I found that with my second application of paint it was really looking quite good. Real thin coats, about 10-12 inches away. If you have a silver or gold car, you might see some stripes in there, so what you want to do is follow up with some vertical passes. Now when I take a closer look I don't see the cloudiness, I don't see any fine scratching. You might see some bumps, but that's okay. You'll have to look very close when the repair is done to see those bumps. From a normal distance you won't notice them. So we wait 5 minutes and we shake up our clearcoat can for about 60 seconds, and nd we'll put on one light coat of clearcoat. And now we'll follow up with a fairly heavy coat. You'll notice how much slower I move from left to right, making sure to overlap about 50% with each pass. Within 10 minutes pull your paper, pull your tape, and you have a virtually new bumper. You can wash the car, wax the car, it is permanent. STEP 1: Mask panels and trim around the repair area. STEP 2: Sand with coarse sandpaper using firm pressure. STEP 3: Wipe away dust and clean with wax and grease remover. STEP 4: Fill scratches with supplied putty and spreader. STEP 5: Scuff area with grey pad. STEP 6: Apply a thin layer of primer. STEP 7: Wait 2 minutes, then apply a heavy layer of primer. STEP 8: Sand primer until it feels smooth using fine-grit sandpaper. STEP 9: Apply thin layer of factory-matched paint. STEP 10: Wait 5 minutes, then apply a light layer of clear coat. STEP 11: Wait another 5 minutes, then apply a heavier layer of clear coat. This kit and process can be replicated on any plastic bumper.
