This is a 15cc bottle of Lucky 7 RC Air Seal Engine Sealant. Lucky 7 Air Seal is a fast drying, wicking sealant that does not require engine disassembly! Simply apply it topically to the carburetor neck and backplate seams, and let dry. If your nitro engine has an air leak, it can make the engine run erratically. To avoid this it is a good idea to seal up the carburetor around the neck and needle valve assembly, as well as the backplate before an air leak develops. Dont roll the dice with your equipment, get Lucky.
NOTE: 30 - 60 minutes dry time is recommended before use. Surface must be clean, and oil free prior to application. It is also very important that the bottle be stored at room temperature.
