I've been changing tyres and thought I'd post my notes for anyone trying the same

To avoid any legal action by Haynes I use the barsteward level of difficulty rather than spanners. I'm rating this "Donald Trump" as the brake calliper is full of spring clips that ping off into the dark recesses of the garage. I much prefer callipers that have separate pad retainers and mounting bolts.
The front version is WIP.

In simple terms, No and no. I have seen the damage these sealants can do to the inside of the rims through corrosion. Personally I carry a puncture repair kit instead, the twisted rubber "string" sort with a CO2 inflator.
Other opinions/options are available.
