I have no idea what "flick, rotate, wait, repeat" means. I usually put sealant in, seat it with a CO2 cartridge, pump up to 60psi with hand pump.....rotate wheel every direction to get sealant moved around.
*****disclaimer: If at anytime none of this seems to work, I throw the tire toward the wall as hard as I can while cussing so loud my neighbors can hear me. I proceed to the fridge, grab a beer, THEN repeat. I have never had to do this more than twice!
