nskyline, yes 3M has automotive products....a whole wide range of it actually. from interior cleaning,restoration to maintenance and also exterior cleaning, restoration and maintenance. i have alot of 3M automotive products as my dad works in 3M. i think 3M did advertise their fuel system cleaner on Hypertune for a few issue's. price and where to get i really have no idea but i can always ask my dad who their distributor or dealers are. i dunno why 3M automotive products not very famous here in malaysia though.....i see alot of ppl using 3M products in overseas forums.
and yea, i use Redex too....my club member's company used to print the labels for Redex...and he got very cheap for a few boxes. so i bought a few bottles and use. pretty much the same ler i would say.
