Just Paint It Up
If the dent is nothing more than a simple flaking of paint or scratch on the surface, you can fix it just by a simple coat of paint. However, remember to use sandpaper to remove rust or paint scrapes before applying the prime and paint.
Use A Rubber Plunger
If it’s a sizable ding with no crease in the middle, using a rubber plunger would be the best solution. It can pop back the steel surface if it hasn’t been creased badly. Place the plunger over the dent after moistening its rubber edges and pump a couple of times to establish a suction. Pull the plunger towards you. With a little force, a couple of tries will be sufficient to pull out the dent. The plunger method will work if the surface is large such a fender or door and made of metal
Try With A Hammer
If it’s a small dent on a steel surface, try to repair it with a flat-ended rubber mallet. It is firm enough to fix a dent in a car but is less likely to leave any ugly marks on the surface. Wrap a flat metal piece with a piece of rag and place it directly on the dent. Now, use the mallet to bang the area from the underside.
Use a small hammer for a small ding and a big one for large car dent repair. Besides, be very careful about not to bang the surrounding area of the pitted part as it is likely to create a few more bumps.
Glazing Putty For Tiny Dings
Glazing putty is an excellent option for filling up the places with chipped paint or tiny dimples. Apply it to the spot with a putty knife and then use primer and paint as the final touch ups. It’s very simple as you just have to follow the directions on the package.
