Cobra Motor - Cleaner and Thinner for 2K Lacquer - 30mL

The technical thinner from Ammo that makes the difference between a correct varnish and a perfect mirror finish

When working with the Ammo Cobra Motor 2K Lacquer, viscosity control is not a secondary detail: it is the factor that determines whether the final layer flows and levels on its own or if the dreaded orange peel texture appears. This technical fluid, reference AMIG2263, has been specifically formulated to work in conjunction with that two-component epoxy lacquer, something that a generic solvent cannot guarantee.

Main function: viscosity adjustment for airbrushing

The Cobra Motor 2K Lacquer is mixed in a 2:1 ratio with its Hardener catalyst. Once both components are combined, this thinner is added in the necessary amount to adapt the fluidity to the current conditions: ambient temperature, airbrush pressure, and the type of finish sought. By reducing viscosity in a controlled manner, very fine wet layers are achieved that extend and level on their own, eliminating spray marks and achieving that characteristic reflective surface of high-end slot car bodies and automotive models.

Second critical function: cleaning the airbrush after each session

The two-component epoxy resin has a limited working window. Once the curing process has begun, conventional acrylic cleaners are unable to dissolve the residues. This product is the only compatible agent for thoroughly cleaning the needle, nozzle, and body of the airbrush after applying the 2K Lacquer, completely removing any trace of resin before it solidifies and blocks the internal parts. A step that has no shortcuts if we want to preserve our tools.

Application tips

• Mixing sequence: First combine 2 parts of 2K Lacquer with 1 part of Hardener catalyst. Then incorporate this thinner until the desired fluidity is reached.
• Working environment: Spray a few drops of water into the air of the workspace before starting to settle the suspended dust. Always hold the piece by its interior with a support; contact with fingers can create craters in the finish.
• Airbrush pressure: It is recommended to work at low pressure, around 1 bar (14 psi). Apply a first thin sealing layer, let it evaporate for about 2 minutes, and then apply the main layer in a continuous and even pass.
• Drying and protection: Cover the piece with a clean lid during drying (24-48 hours) to prevent dust from adhering to the still fresh varnish.
• Cleaning: Clean the airbrush immediately after each session with this same product to avoid blockages from cured resin.

Safety and important information

Unlike the paints in the Cobra Motor range, the 2K Lacquer and this thinner are toxic and flammable products. Their use requires a mask with filters for organic vapours, protective goggles, and a well-ventilated space or an extraction booth. Keep tightly closed, away from heat sources, and out of reach of children.

Frequently asked questions

Is this thinner compatible with other lacquers or varnishes from the Ammo range?

No. This fluid is specifically formulated for the Cobra Motor 2K Lacquer. It should not be used as a thinner for water-based acrylic paints or other varnishes from the Ammo range, as the chemical composition is different.

How much thinner should I add to the lacquer and catalyst mixture?

There is no fixed ratio: the amount depends on the ambient temperature, airbrush pressure, and the desired finish. The recommended practice is to add it progressively after mixing the lacquer and the catalyst (2:1) until reaching the fluidity that allows for clean atomization without the layer running.

Can I use a conventional acrylic solvent to clean the airbrush after using the 2K Lacquer?

No, it is not effective. Water-based or alcohol-based acrylic cleaners do not properly dissolve the two-component epoxy resin. It is necessary to use this same thinner to ensure complete cleaning and prevent residues from hardening inside the airbrush.

How much time do I have to work with the mixture once the catalyst has been added?

The 2K Lacquer begins its curing process as soon as it is mixed with the catalyst. The working window is limited, so it is recommended to prepare only the necessary amount for each session and clean the airbrush immediately after finishing.

Can the finish be polished if any dust particle falls during drying?

Yes. Once the lacquer has fully cured, it is possible to treat small imperfections with suitable polishing compounds for models. Covering the piece during drying with a clean lid is the best preventive measure.

The Cobra Motor 2K Lacquer Thinner and Cleaner (AMIG2263) by Ammo of Mig Jimenez is a professional-grade technical solvent engineered exclusively for use with the Cobra Motor two-part epoxy gloss clear coat. Available in a 30 ml jar, it allows scale modelers and slot car enthusiasts to fine-tune mixture viscosity for flawless airbrush atomization, preventing orange peel texture and delivering a true mirror-like finish on scale car bodies. It also serves as the only effective heavy-duty cleaner for removing uncured 2K epoxy resin residue from airbrush needles, nozzles, and bodies. Compatible with Cobra Motor Hardener. Essential for anyone working with 2-component lacquers in scale modeling, slot car preparation, or static scale model finishing.
