DIY shielding paint can be made with a base and conductive powder
While I could not find the ingredients of Crimson Guitars' shielding paint, I did find information on DIY shielding paint.
One recipe for DIY shielding paint involves mixing crushed pencil leads with Elmer's glue. This creates a shield that protects the electronics inside the guitar from interference caused by RF radiation. When using a metal box as a shield, it must be connected to the ground of the electronics for it to be effective.
Another option for DIY shielding paint is to use Rustins G-Shield, a water-based, cross-linking acrylic resin containing natural exfoliated graphene. G-Shield provides reliable shielding from high-frequency electromagnetic fields and low-frequency electrical fields. It is also solvent-free, with low emissions and lasting corrosion resistance. However, some users have noted that it is not very electrically conductive and can be slippery, making it difficult for other paints to adhere to it.
Shielding paint can also be purchased from various manufacturers, such as Solo Pro, which offers a black conductive shielding paint that is water-based, inexpensive, and has good spread and adhesion. This paint contains water, pure acrylic binder, graphite, carbon black, additives, and preservatives. Users have found it to be effective, with one coat providing full conductivity.

Bases can include polyurethane, shellac, or acrylic craft paint
Crimson Guitars offers a 30ml bottle of Rear Guard Shielding Paint to protect your guitar's electronics from radio frequency interference. While the ingredients of Crimson Guitars' shielding paint are not publicly disclosed, DIY guitar shielding paint typically consists of two main ingredients: a base and a conductive powder. Bases can include polyurethane, shellac, or acrylic craft paint.
Polyurethane, shellac, and acrylic craft paint are used as bases to hold the conductive powder in place. Of these options, acrylic craft paint is the easiest to work with and is the least likely to chip off. When choosing a base, it is important to consider its compatibility with the conductive powder to ensure a smooth and effective application.
Conductive powder is available in various materials, including graphite, powdered copper, aluminum, silver, nickel, and even gold. Graphite, copper, and aluminum are recommended choices due to their effectiveness and availability. It is important to experiment with different mixtures to achieve the desired consistency and conductivity.
In addition to pre-made shielding paints, guitar enthusiasts also have the option of using metal tapes, such as copper shielding tape, for shielding their guitars. These tapes provide high conductivity and a matte black finish. However, some people may find them more challenging to work with compared to shielding paints.
Overall, the base of the shielding paint plays a crucial role in holding the conductive powder, ensuring the paint's adhesion, and providing a smooth finish. By selecting appropriate bases such as polyurethane, shellac, or acrylic craft paint, guitarists can effectively shield their instruments from interference and achieve their desired aesthetic results.

Conductive powders include graphite, copper, aluminium, silver, nickel, or gold
While I could not find the ingredients of Crimson Guitars' shielding paint, I did find that conductive powders are used in DIY guitar shielding paint. These powders include graphite, copper, aluminium, silver, nickel, or gold.
Conductive powders are mixed with a base to create shielding paint. The base holds the conductive powder in place. Polyurethane and shellac are good choices for a base, but ordinary acrylic craft paint is the best option because it is easy to work with and does not chip off.
To make DIY guitar shielding paint, you need to add the conductive powder to your base until the mixture is spreadable but very sandy and thick. You may want to experiment with the consistency on a spare board, adding more powder as you go.
Guitar shielding paint is used to protect guitars from radio frequency interference and reduce the amount of hiss in the signal. It is also used to protect electronics inside audio equipment from interference caused by RF radiation. When using a metal box to shield electronics, it must be connected to the ground of the electronics to effectively shuttle off incoming radiation.
There are many brands of pre-made shielding paint available, as well as metal tapes that can be used for shielding. Copper shielding tape, for example, is recommended for its high conductivity and ease of application.

Commercial shielding paints include Rustins G-Shield, Solo Pro Black, and Crimson Guitars Rear Guard
There are several commercial shielding paints available on the market, including Rustins G-Shield, Solo Pro Black, and Crimson Guitars Rear Guard. These paints are designed to shield guitars from radio frequency interference and reduce the amount of hiss in the signal.
Let's take a closer look at each of these products:
Rustins G-Shield
Rustins G-Shield is a water-based shielding paint that contains natural exfoliated graphene. It is designed to provide reliable shielding from high-frequency electromagnetic fields and low-frequency electrical fields. The paint is solvent-free, with low emissions and lasting corrosion resistance. It is available in tin or aerosol form and is black in colour. Some users have noted that while it works well for shielding, it may not be as electrically conductive as other options.
Solo Pro Black
Solo Pro Black is a water-based conductive shielding paint that is easy to use and provides excellent coverage. It is made from water, pure acrylic binder, graphite, carbon black, additives, and preservatives. This paint is also inexpensive, nearly odourless, and has good adhesion. Users have reported that one to two coats are usually sufficient to achieve proper conductivity, making it a cost-effective and time-saving option.
Crimson Guitars Rear Guard
Crimson Guitars Rear Guard is a conductive shielding paint designed to protect the electronics in your guitar. It comes in a 30ml bottle, which is the ideal quantity to completely cover the insides of your control cavities. This paint is easy to use and only requires a small paintbrush for application. It is important to shake the bottle well before use and be careful to avoid contact with skin and eyes.
By using these commercial shielding paints, guitarists can effectively shield their instruments from electromagnetic and radio frequency interference, improving the overall performance and sound quality of their guitars.
