About patch. Does anyone know a service center (or vulcanizing shop) around the Thomas Morato Ave area (Timog St) in QC that uses so called cold patch system inside rim instead of using high temperature? How many still use the latter? Also service center with good security because you don't want to be vulnerable with a car inside a corner.

You can dm me if it is not allowed to post a shop name.

I assume it is safe to patch a tire that was already plugged (pasak). Thanks.
