reading orange seal dip stick question

[ted]

Orange seal comes with a handy dip stick for periodically checking sealant level.

It has a roughly 1 inch serrated surface on the end. Should the sealant be that deep (i.e. 1")? Half that?

I'm looking for guidance on how deep is good to go and how deep means time to add some more.

I never read the directions, but I use that stick as a valve stem reamer. I've found that dipsticking isn't very precise, especially with supple tires. Fortunately the keeping of perfect sealant level is an imprecise science, more is good, less is probably fine, and starting from zero is the only clear path. So, dipstick when sealant boogers/skin make addition difficult, and for figuring when to add, use the force/shlosh (shake and listen) test. Works for me!
