Why I refuse to use tire sealants on customer vehicles

I know a lot of shops swear by those aerosol sealants for a fast fix... but I've seen them ruin tire pressure sensors and create a mess inside the rim. It's a lazy shortcut that compromises long-term reliability. I'd rather take the extra time to properly patch from the inside, even if it means turning away quick cash. Recently, a customer came in with a wheel that was practically glued shut from sealant residue, and it took me an hour just to clean it up before I could assess the actual puncture.

Respect the stance, but from what I've seen, not all sealants are created equal. Some of the newer, latex-based formulas are designed to be less harsh on TPMS sensors and wash out more easily. I've had decent results with them in a pinch, but they're still a temporary fix at best. The key is informing customers about the potential cleanup and sensor risks beforehand.

Agree with @maxf54 on the info part. I tried a newer latex formula when my tire got punctured off-road, and it held air for a couple days until I could properly patch it. The sensor was fine, but I made sure to flush it out ASAP. Key is managing expectations, just like maxf54 mentioned.

Which newer latex brands wash out easiest?

Not all sealants are created equal" got me thinking. Actually had a buddy who tested this out on his gravel bike last summer. He used some newer brand called Stans Race or something like that. Long story short he flatted on a ride and the stuff washed out with just water and a rag, no crusty residue left behind. His TPMS sensors were totally fine too. Said it was way easier to clean than the older orange seal stuff. So yeah, some of those newer formulas are legit easier to flush out.
