Perhaps it's just me but I just can't get on with ACF50. Tried it in the past via a compressor and the bike just looks like a POS after the 1st ride and it's such a faff to get off come spring time if you want all of your bike looking nice. I know it doesn't last as long a d you need to apply it after every ride but I much prefer FS365. I have treated the hard to get at areas like the rear hub with XCP but for the rest of the bike unless you're riding it every day FS365 is IMO a better option as amongst other thi vs it's far easier to apply and your bike still looks decent afterwards but each to their own.
