What should I do if the rear shell of the car is cracked, and what should I do if the plastic shell

Generally, if a small area is cracked or broken, it can be done with all-purpose glue. If there are not many plastic scraps, they can be put together like building blocks.

If the gap between the fragments is large, we need to use a hot melt gun to bond it. If the hot melt gun is not good, you can use the plastic steel cement used in the market to repair pipes. The plastic steel mud will be very hard after drying, and some skills are needed in the way to use it.

However, the area that has been broken is large, and the stress point cannot be found when bonding. Styrofoam can be used.

Shape it into a suitable shape and apply glue to the hole as a backing. If one piece doesn't work, you can use two, three, or five pieces together. With the backing, it is much easier to bond together.

If the plastic scraps are also missing, we can put foam board inside.

Or corrugated cardboard.

After the glue is fixed, use putty powder.

Just smooth it out. Probably after the plastic surgery is completed, when the putty powder is dry, it is time to polish and spray paint. However, it is best to let the garage do the painting. Nowadays, they all use computers to mix paint, and it is easy to have color differences by themselves.

You can consider repairing it, and if it can't be repaired, replace it directly.

**Buy a do-it-yourself swap out.

Now the front and rear bumpers of cars are generally plastic, so you don't have to worry about rust and you can leave it alone, save money and buy a sticker to stick it on.

Talking about the rear bumper, right? You can get a new one.

You can go to the decoration shop to repair or replace, and you can't glue it yourself.

If the back shell of the car is cracked, then we can go through the insurance process, we must be careful when driving ourselves, and we must drive under the premise of ensuring safety.

Personal advice.

1. Go to the repair shop to spray paint, weigh the **, and see if you take insurance.

2. Buy a touch-up pen and apply it to the scratches.

3. Buy some personalized car stickers and cover them on the scratches.

4. Buy a mixture, wipe it in a straight line on the scratch, and after the scar disappears, wipe it with a finer mixture and then wax it.

5. It can be repaired at one time when necessary.

Fixes. 1) Lacquer pen repair method. Applying a paint pen of a similar color to the scratch is a paint pen repair method. This method is simple, but the adhesion of the repair paint is not enough, and it is easy to peel off and difficult to last.

2) Spraying method. Scratches are repaired using traditional touch-up paint methods. The disadvantage is that the damage area of the original paint is too large, the repair time is too large, and the effect is difficult to be satisfactory.

3) Computer paint mixing spraying method. Combined with the deep scratch repair technology of computer paint mixing and new process methods, this is a fast technical repair, but it requires accurate color matching, the repair area is reduced as much as possible, and then after special solvent treatment, the new and old topcoats can be better integrated to achieve optimal adhesion.

In addition, if the damage to your car paint is not very obvious or you don't want to use a touch-up pen, there is actually another way to solve it - stickers. It's also good to cover up scratches with your own favorite stickers, and it's better to look at than with a touch-up pen.
