Does a touch up pen corrode the original car paint, does a car touch up pen corrode the original car

Yes.

The harm of the touch-up pen to the original car paint:

In fact, touch-up pens can only be used temporarily. For deep and larger scratches or exposed primers, there is no way to achieve the same effect as touch-up paint, there is no gloss and there is a certain color difference, the effect is not very ideal. The main ingredient of the touch-up pen is paint, but it also contains some solvents, which can dissolve the paint, and some inferior touch-up pens have a higher solvent content and will corrode the original car paint.

After using the touch-up pen, many car owners find that it looks like adhesive tape from a distance, which is very ugly and conspicuous. For the small scratches of the white body, the toothpaste is more useful, but be careful not to use granular toothpaste, but it will become a scrubbing effect, and the damage will be more serious.

This thing that will not corrode the paint is originally anti-corrosion with paint.

The touch-up pen is filled with paint and solvent, and the solvent can dissolve the paint, so the touch-up pen will corrode the original paint.

The principle of the touch-up pen.

Automobile paint is generally baking paint, and the car begins to be painted after the welding and other processes are completed in the workshop. First, the primer is sprayed, the bare car shell is immersed in the paint tank, the primer is dried at 200 degrees after being removed, and then sent to the dust-free workshop to be sprayed with electrostatic spraying, and then continued to dry at 200 degrees, and finally a layer of varnish will be added.

The paint brush will have a color difference with the color of the body, so it is better to dispose of it by direct polishing and waxing. The function of the paint brush is to cover the iron sheet of the leaking primer to prevent rust, and the usual scratches can also be repaired, but the color is still very different from the original car paint. For temporary use only.

Role and usage.

The touch-up pen on the market has a few dollars and dozens of dollars, the quality can not be guaranteed and can not be controlled, the touch-up pen also has a good quality, the characteristics of the effect of the car touch-up pen: fast drying, due to the use of environmental restrictions, the touch-up pen must have the characteristics of fast drying at room temperature, otherwise it is easy to cause flow or dust and other effects on the appearance.

Versatility, the touch-up pen is made according to the standard color tone, with a certain degree of versatility; However, as described in the above color grading principle, it is not suitable for a wide range of vehicles with different degrees of aging, and the color difference may be greater than that of one-to-one color painting.

No, a touch-up pen is a car scratch repair tool that can be used to repair, cover up and fill in small scratches or paint peeling areas.

Although the paint brush can fill the vacancy, block the contact between the air and the surface of the car body, and have a certain anti-rust effect, it can not replace the professional car anti-rust paint, if the car paint is damaged, it is recommended to go to the 4S shop or a professional repair shop for paint repair, so that it is more secure and more worry-free.

Precautions for using touch-up pens:

1. For smaller scratches (such as small stone chips, slender hard object scratches), as long as you buy a paint repair pen, you can apply it directly to the scratches with the included brush, and for deeper scratches, you can achieve the ideal effect as long as you apply it several times.

2. Because the paint brush is very different from the professional painting process, there will be a slight color difference with the original paint after the paint is filled, and the paint film will be completely dry for 2 to 3 days, and then use 2000 water sandpaper or abrasive for grinding and polishing The effect will be better.

3. Do not unscrew the pen cover when the product is placed horizontally or upside down, so as to avoid the paint escaping.

No, touch-up pens are paints and are generally not mixed with other paints after they have dried, except with corrosive chemical liquids such as banana water...

Generally speaking, it is impossible to corrode the original car riding with a paint pen, it has no corrosive ingredients in it, and it is just a game, so there is no need to worry about this, but the effect of the paint pen is definitely not as good as that of lacquer.

No! Touch-up pens should only be used in small areas where the paint has fallen off! And there is an error in the color!

Yes! Because the ingredients are different.

Yes, it won't rust.

It can be repaired with a touch-up pen. In addition to the more common collisions, scratches, and long-term parking rust, there is also a point collision caused by the small stones bounced up by the two tires of the front car when driving, which will make the paint surface peel off one by one, resulting in small rust spots.

As long as the scratches are treated, the exposed primer can be covered and the touch-up paint will not fall off, after all, as long as the exposed primer is in contact with moisture in the air, rust will not occur; But at the same time, if the scratches have rusted before treatment, and the paint pen is used directly without rust removal, the rust inside will continue to expand in the future.

The most effective way to deal with rust on the surface of the paint is to first polish it with sandpaper, then polish it again with more than 1000 mesh fine sand, and then spray it after continuous polishing; Therefore, if there is no rust on the paint surface, the surface oxidation is covered by the paint repair pen, as long as the coverage is complete, the galvanized sheet inside does not come into contact with the air, it will not rust.

Touch-up paint pen is a kind of car scratch repair tool, according to the original color of the car paint to choose the right model can be repaired by yourself, in the small scratches or paint peeling place after the paint brush is covered, fill the scratches, the composition of the paint brush is generally the original car paint, because the car model is different, so different cars can only use a special paint brush.

Of course, there is no problem, the scratched place of the car will not rust due to the touch-up pen!

No problem at all, rest assured.

At first glance, you can tell that it is a thrifty child's paper. I also used a paint pen to repair the scars and deal with them later.

You can re-spray it with sandpaper and flatten it.

You expand the area of scratched touch-up paint a little bit and you'll be fine. You can see it, but it doesn't rust.

OK. Before the car is painted, if the scratch part is deep, it is necessary to polish off the paint surface first, and at the same time polish off the possible rust on the metal, and then use putty to flatten, and wait for the putty to dry thoroughly before re-painting. If you don't treat it, if there is rust on the scraped metal sheet, it is easy to bulge and peel off the paint after painting.

When the scratch part is shallow, you can spray paint directly. If you use a touch-up pen, you will need to use sandpaper or a polisher to sand off the touch-up area before you can spray it.

To be honest, this paint pen is divided into people and injuries, and it doesn't matter if the small paint is painted, but if the long scratches and the kind of hands-on ability that can feel the dents is not strong, it is really not recommended, and it is even more ugly if the repair is not good.
