I always have it redone in proper vulca shops using the patch. In my observation no air is lost using the plug, I have a tpms to monitor it.
I'm sure they used oil because the main technician said the assistant get some oil to make easy to insert and I saw him with an old can with oil from the engine oil replacement area and got screwdriver to let the oil in. They didn't use the repair kit glue. The assistant said it was alll oil and rubberized strings. But I'm beginning to worry because I read the hole should be rough and not smoothing it with oil. Also I read plug/pasak can damage the steel belt that keeps the tire's structure intact and can cause bulge in the spot.

If I'd have patch done tomorrow on the spot by opening up the rim. What would likely happen since the hole is now bigger than the original? Would it cause other side effect. A new tire costs 11,000 pesos.
