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?
