This product is attached and the specified amount is used as the main ingredient, but when adding a paint by addition, cracks enter and it is in a state of unusable. I expected that it could be used very conveniently, but it was a ridiculous item.
It keeps it on the can of curing agent and keeps it, but it is broken when it noticed. Spill over the nozzle during injection. If you improve such as bending the tip, the price is also cheap so I am satisfied.
