nahi peyare bhai not clayed, its autofinesse sealant which giving such fresh look 
dear 3m perfect it show car wax falls in natural carnuaba range so u cant compare duarability with syn waxes, sure nxt more duarable but 3m past wax gives drippling wet look specialy on lighter cols as in dark cols it lacks depthness. if u compare 3m performance finish ( synthetic wax ) with nxt than sure 3m better results and duarability than nxt ( based on personal experince )
autofinesse having 2 types of sealant one is for 3 months protection and other is for 6 month duarability. since www.detailingcrew.com is now authorize dealer in pakistan so both avilable there at very attractive rates, the one i applied is autofinesse tough coat sealant with 3 months protection, its spray type, for best results car surface should be well prepared and application must be very even otherwise its strong enough and u have to bear that unevenness for next 3 to 4 months hehe
yes its easy to buff
