To use valve grinding paste:
1.Apply a small amount of paste to the valve seat. You can also apply it to the valve face.
2.Avoid contact with the valve stem and guide.
3.Grind the valve in the normal manner. This typically involves rotating the valve against the seat using a valve grinding tool or a lapping tool.
4.Continue grinding until you achieve a uniform seat with the desired appearance. This usually means a smooth, matte finish with no visible pits or scratches.
5.Clean the valve and seat thoroughly: to remove all traces of the grinding paste.
