My uncle is a sprayer and he said these are expensive but the best things ever to be made so i paid £30 and i got 2 and a polish to go over it once the scratch has gone... the temperature has to be right when doing it but honestly its.... see a scratch go over it and apresto its gone no waiting or polishing etc it just disappears i am just waiting till i get them i will do a video to prove how amazing they are but... they might be crap and i have just thrown £30 away but from what i have heard and seen i have confidence cant wait get rid of this 1 horrible scratch on the rear arch of my car :yum:
