Troubleshooting
Putty is not adhering to the metal surface

Setup, Compatibility & Care
To use this kit, start by cleaning the surface thoroughly with a degreaser or alcohol to ensure proper adhesion. Cut the required amount of putty from the stick and knead it by hand until it achieves a consistent color. Apply the compound to the area, ensuring you overlap the edges of the crack or hole. While it cures in two hours, avoid subjecting the area to extreme heat or high pressure until fully cured. This product is strictly for metal repairs. Do not attempt to use this on plastic tanks, as it will fail to bond correctly, leading to potential safety hazards.
