The details of the vulcanising procedure are obscured by the tyre a bit.
"Vulcanizing" is sulphur, heat, and raw rubber. This is just melting rubber to seal the hole, that's all. He damaged the halobutyl inner liner with that marshmallow-roast move.
Yeh, should have been "Vulcanising".
Seems to be some some disagreement as to whether its just melting rubber. Several mentions above of lighting off glue, though I wouldn't have thought that'd enhance adhesion.
On bikes I just use contact adhesive and a bit of old inner tube.No heat but clamp between two coins in mole grips. On cars so far I've only used the tyre string kits, which are widely considered criminally irresponsible in the UK, especially by people who sell tyres. Maybe I/'ll try the BBQ technique.
I don't like his lug nut torquing pattern. Should be a star pattern to keep the rotors from warping. Where is his ASE Certification? Didn't see it hanging on the wall anywhere.
Looked over-tightened to me, so he's following the same standards as you get in the first world from a professional using air tools.
