Well, the current formulation is, however this tin might be 20 years old.
You might have been better off going slower, sparingly to see how it responds.
I would encourage you to stop where you're at and wait a couple of days and see.
You can always ride them anyway but I would plan on it possibly being a display only saddle.
Wipe it down good and get any excess off for now and I would not plan on using anymore.
