What is the relationship between GUNZE SANGYO and GSI Creos?

GUNZE SANGYO is our former company name, which was changed to GSI Creos Co. in the spring of 2001.

The product I got is damaged / defected. What should I do?

We sell our products to overseas customers through our partnered distributers and they handle the customer service for our products.

Please contact with the seller for assistance with your order.

Can I buy your products directly from you?

We don't sell our products directly.

If you are interested in selling our items, let us know via contact form.

I need SDS of your products.

We provide SDS via form in contact page.

I don't know what kind of paint to use.

Please check this "How to" article for a detailed explanation of the different types of paints and finishes.

Can you tell me how to dispose of leftover paint, paint thinner, etc.?

Each local government would have its own disposal method for paint products, so please contact your local government.

As a general disposal method, paint in bottles can be absorbed by newspaper, etc. and disposed of as non-burnable trash after it has completely dried. Thinner can also be disposed of as burnable trash after it has dried naturally. When drying, please place the paint in a well-ventilated shady area, as there is a possibility of ignition in the worst case scenario.

I want to paint a kit with Mr. Hobby products but the color list in the instruction is in different company’s color.

There is a possibility that the colors for tanks and fighter planes may differ slightly from one manufacturer to another, but since we use actual color or reputable material as references for our products, please refer to the color names and information on the color chart to make your selection. If the color is not released by our company, we are unable to determine the approximate color or mixing ratio, so please mix our paints on your own.

I don't know what colors I need to paint my plastic model, so please tell me the color mixing ratio.

We are unable to determine the color mixing ratio for individual kits or motifs, so please contact the respective manufacturers.

I would like to use other kind of Creos paints to paint the kit specified with another Creos paints, can you tell me the corresponding colors? For example, I would like to paint a kit specified with Aqueous Hobby Color with Mr. Color.

For example, I would like to paint a kit specified with Aqueous Hobby Color with Mr. Color.

Some colors are almost the same in several paint series. Please check the color chart distributed on this page to check color compatibility. If there is no corresponding color listed, the same color is not available. Please find an approximate color from the color chart or reproduce the color by mixing colors.

I am having trouble as the painted surface turning white.

This is caused by a phenomenon called "fogging” or “Kaburi”. This problem occurs when moisture is trapped in the paint mist from airbrush or can, otherwise, this is caused by the condensation of moisture on paint surface in drying process. This phenomenon is likely to occur on hot humid day. So avoid painting in rainy day or snowy day. To avoid this when using an airbrush, use accessories with drainage functions such as various types of regulators or Mr. Drain & Dust Catcher, or pay attention to the temperature and humidity of the room when drying. If the temperature is low, warming the parts slightly can also help.

To recover the model from clouded paint, remove the paint with sandpaper before repainting.

Also, if too much matte coating is applied, the matte paint will easily turn white.

Do not spray the paint all at once, and apply thin coat multiple times. Even if it is not matte at first, it would be as it dries.

There are many types of surfacers, but I don't know which one to use.

The number on surfacer shows the texture of the paint. 500 is the coarsest and can fill the rather large scratch. 1500 is the finest and can achieve even surface. Choose the course one if there are large scratches on the surface, and the fine one if you are painting as a base coat. Basically, gray color is used as it is easy to find scratches, but black, white, and pink are also available in consideration of the coloring of the topcoat. Primer surfacers are also available for painting on resin and metal parts. Please select the one that best suits your application. The bottle type surfacers can be applied by brush or airbrush, allowing you to paint even the smallest of details. The standard dilution is 1 to 2 parts of thinning solution per 1 part of paint.

The paint peels off easily.

The most common causes for this problem are

(1) The material being painted is not normal polystyrene resin.

(2) Oil or mold release agent is adhering to the painted surface.

Our plastic model paints slightly dissolve polystyrol to increase the adhesion. When painting on other materials like metals or resin casts that are highly resistant to solvents, please apply a metal primer or primer-surfacer first as a base coat to increase the adhesion before painting.

In addition, the surface of the plastic model may be coated with oil or mold release agent left over from the manufacturing process, which prevents the paint from adhering to the surface. We recommend cleaning the parts with a neutral detergent before painting. After cleaning, be sure to thoroughly rinse off the surfactant from the neutral detergent.

I want to paint on polycarbonate.

We do not have any paints or primers that are compatible with polycarbonate.

Although it is possible to paint on polycarbonate, we recommend the use of special paints made by other companies because problems such as peeling or cracking of the paint film are likely to occur with our paints.

Can linear compressors and airbrushes be connected to other companies' products?

Our airbrush-related products use either 1/8 size (or S size) screws, which is a general standard, or PS (thin), which is our own standard, for the connection part. PS241 Mr. Joint (3-piece set)," a joint that can convert PS (thin) size joints to 1/8 size, is available as an optional accessory. Please check the joints of your equipment and use the appropriate joints.

Can I disassemble the airbrush by myself?

The structure of an airbrush itself is simple, so if you understand the structure, you can disassemble and maintain it by yourself. However, there are some parts that are at high risk of damage, such as the tips of the needles, so please be careful and do so at your own risk.

The needle on my airbrush does not move.

If the airbrush needle does not move, paint may be sticking around the needle, preventing it from moving, or the needle chuck screw may be loose. Remove the airbrush shaft cap at the rear of the airbrush and tighten the needle chuck screw. It is also necessary to remove paint and other contaminants from around the needle. Fill the cup with tool cleaner, backflush carefully, and wipe the area where paint has accumulated with a brush.

Paint flows back to the push button or trigger side of the airbrush.

The cause may be that the needle packing, which prevents paint from flowing to the push button side, has deteriorated, or that paint has adhered to the needle and expanded the packing. Please clean the needle.

If tool cleaner is left in the cup for a long time or some solvents from other manufacturers are used, as they are more aggressive than the solvents normally used for model paints, the needle packing will easily deteriorate.

The compressor pressure is low/dropped.

The linear compressors we make are highly durable and are fully inspected prior to shipment. If the pressure is low, the cause is often a peripheral device or connection. Re-tighten each connection. In particular, please check the area around the air exhaust of the compressor, as it may have loosened during transportation. If peripheral devices such as regulators are connected, we recommend that you remove them and check the pressure with the handpiece and compressor only. Also, if the total distance of the hose from the compressor to the airbrush is long, for example, if there are many devices connected before the compressor (many times through joints) or if multiple hoses are connected and extended, the pressure coming out of the airbrush will be reduced.

The compressor pressure is higher than the specs.

Our linear compressors are measured at our factory in Kanto, Japan.

In areas where the power supply frequency is in the 60Hz band, the compressor would work in higher power.

This is not a malfunction.

Can I change the paint nozzle of an airbrush to a different size?

All of our airbrushes use specially designed nozzles and needles, and it is not possible to use a different diameter nozzle.

The push button on the airbrush does not work properly.

If you are experiencing poor movement when pulling the airbrush push button back, the needle packing may have expanded, or paint may be sticking to the needle. Remove the paint from the surface of the needle by wiping it off with a brush moistened with solvent (be careful not to touch the tip of the needle).

If the push button does not move smoothly when pressed, paint may be stuck to the piston or the piston packing in the air valve may be swollen.

While using the compressor, water spurts from the airbrush and the paint job fails. Is there a problem with the compressor?

No. This is because water in the air is compressed and condensation occurs in the hose, which then comes out with the air, not a compressor failure. Even if it is not raining, the air contains a lot of moisture, so you must be very careful. The remedy is to put a drain between the compressor and the hose. Condensation may also occur in the hose between the regulator and the airbrush. In this case, it is a good idea to install a regulator with a drain function or a drain and dust catcher on the airbrush and catch the water there. Using them will improve the situation considerably.
