My brother-in-law recently used my professional tire pressure gauge for his bike and returned it with a damaged sensor. This might seem minor, but inaccurate readings from faulty equipment can lead to serious underinflation issues on customer vehicles. I had to replace the gauge immediately to avoid compromising my work. Please consider setting clear boundaries about tool use with relatives to prevent similar situations. It's a small step that protects both your livelihood and family relationships.
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.
