Sealing light tyres that leak from thin sidewalls eg Schwalbe

Seems a few have had problems keeping racing ralphs and similar (eg. Specialized S-Works Control) inflated when new. Had the same problem followed the standard practice of shaking the wheel so sealant covered the sidewall, so experimented and think may have found a way of doing it simply and quicker that I haven't seen suggested elsewhere. After two days still couldn't get tyre to seal, Put wheel in bath of water to cover the valve and found dozens of small pin pricks in the tyre wall leaking air very slowly.

So I tried:- Mount tyres on rim as per normal, including the correct quantity of sealing liquid of choice. Place a tube or rod the same size as the axle (or the axle if you wrap it to protect it) in vice so axle is vertical. Put wheel and inflated tyre onto rod so it is horizontal and spin the tyre! Turn wheel over and repeat. Do this a couple of times. This makes sure that the sealant runs over the sidewall and gives it a chance to seal the pin holes in the wall. Rationale = Just letting the tyre sit horizontally doesn't let the sealant cover all parts of the sidewall, also shaking the tyre doesn't give the sealant enough time to seal all the 'pin pricks', spinning it gives more time.

Previously had given up on one set of tyres and put tubes in, tried the above on another set and within an half hour had the tyres holding pressure.

Either this works or it was just plain dumb luck!
