DIY Car Repair: Bumper

All that a DIY bumper repair needs is patience and a couple of hours. Just follow these few simple steps:

Scrape the damaged spot. Properly rub the damaged spot for a while with a plastic surface clear. Rinse with water and use a prep solvent (a mixture of equal amount of repair adhesive and hardener) after the area is dry. Finally, polish the area with 80-grit sandpaper.

Repair the cracks. Hold the broken pieces together with a special fiberglass repair tape and apply a layer of adhesive to the damaged spot. You can use another layer for added durability and firmness. Polish the spot with 80-grit and then 120-grit sandpaper. Apply a coat of wet, flexible sealer, and then a second layer after the first one is dry. Finally, sand with a piece of 400-grit paper.

Paint the area. Wet-sand the bumper and remove debris. Spray two or three coats of paint matching to the original color of your car. Then, apply two coats of a mixture of clearcoat and hardener, with appropriate dry time in between. Let the clearcoat sits on the area overnight before sanding with 1500-grit paper.

DIY Car Repair: Fender Bender

Most fender bender damages require just a paint job. However, follow these steps in case of other damages:

Dent repair. Use a suction cup dent puller to pull the dinged spot back to the surface level. Then, use a small hammer carefully to flatten the place with many small taps.

Bumper scratches. The plastic bumpers easily pick up scrapes and large cuts. However, you’ll just need a suitable bumper filler compound to repair such damages. Give the finishing touch by polishing with sandpaper and then giving a wax job.

A DIY auto repair will not look like a professional job, leading to dropping the resale value of your car. However, homemade repair jobs are handy in case of emergency and saving you a sizable amount of bucks.
