It's generally not recommended to mix different types of the best gun lube. Different types of lubricants can have different chemical compositions that may not be compatible with each other. Mixing different types of lubricants can cause them to break down, separate, or become less effective. Additionally, mixing lubricants can make it difficult to determine the appropriate amount of lubricant to use and where to apply it. It's best to stick to using a single type of high-quality, gun-specific lubricant for each of your firearms.
