Topped off my wheels with 1.5 ounces Orange Seal Endurance in November and removed one of the tires a week ago. There was probably 5 drips of liquid and the rest had formed a complete snake skin covering the the tire’s interior. Peeling it off was a fun 35 minute treat.

If I top it off monthly with another 1.5 ounces, after a year, the tire will probably weigh a pound more with all the dried sealant. However someone did say to add fresh in it to keep the existing from congealing. Will have to try that. May have to set a monthly reminder on the phone.
