How to Double Hydro Dip a Gun

Hydro dipping helps to enhance the surface of your gun and offers complete concealment. Double-dipping a gun involves dipping the gun twice to achieve the best results.

Step-by-Step Procedure

  • The first step of double dipping involves cleaning the gun. Use isopropyl alcohol to clean. Then either scuff the gun or sandblast it for the coating to stick to it properly. Next, you’ll want to prime the gun to ensure proper adhesion of the paint. The third step involves applying the base coat that determines the overall look of the gun. For the fourth step after the paint is dried, tape up half of the gun to prep it for dipping. In the fifth step, the printed film is placed on the water that is between 80-90 degrees, with no air trapped between the film and the surface of the water. The film is hydrated for about 60 seconds and then the activator is applied and the gun dipped the first time. Make sure to rinse off all the PVA from the dip and dry it thoroughly.
  • When taping, it is important to use blue tape or a very low tack tape. This helps to prevent pulling the pattern off excessively when trying to pull the tape off. In the second dip, ensure that there is at least an eighth of an inch of the film showing from the first dip so that the second pattern will overlap the first pattern. This also makes sure that the final pattern looks seamless.
  • Double dipping is ideal for guns with many different intricate parts. When dipping the gun for the second time, it is essential that the gun is dry and rinsed to achieve the best results. To keep the film from rolling over the edges, you can apply tape on the sides before getting it in the water. The film is held by dividers in the water, and you can pull out any wrinkles in the film using air from the activator gun.
  • After hydrating the film for about 60 seconds, you can apply an activator along the film. Hold the gun at a slight angle when dipping the second time to allow all the film to cover the entire part. Once the gun is submerged in the water, move the film around to move all the excess film from the dip, and then pull it out of the water. The main advantage of using the blue tape is that you can let it sit underwater and it can release some adhesive to make pulling it off much easier. It is also important not to push down on the blue tape very hard when applying it. Apply just enough pressure for the tape to stick so that it can come off easily.
  • Pulling the tape in the water ensures that the pattern stays intact. You may need to touch up some areas that trap air and miss the pattern. The gun can be dried using conventional heating or air drying, depending on your preference. This is usually done at lower temperatures to enhance the final appearance of the gun.
  • The final step is to apply a clear coat, which is highly recommended for a hydrographically decorated gun. This gives it a cleaner finish and helps to seal the ink. The clear coat is applied after the gun is dry. A second coat may be necessary, depending on the gun and requirements of the customer.
