Ditto on what
@craze1cars and
@Sandroad say.
Also found your instructions that seem to imply to screw unto you can’t screw any more to be very sound advice.
And on a more serious note you can refill the canister with aftermarket brands a lot cheaper than buying the can and parts from Honda.
Here is what I copied a while back but I can’t remeber who posted it.
Tire Repair Kit cheap refill:
The dealer told me that I needed to order an entirely new kit even though it appeared to me that just the sealant cartridge could be replaced. After some research I ordered the Slime 10179 refill kit from Amazon.

While looking almost identical, the knob and valve are slightly different shape. Easy fix was just to swap those parts with the ones on the used component and now it’s good as new. Highly recommend this solution. I actually think the OEM is a Honda branded Slime unit. Chemistry and test of parts seem identical.
