Isn't autosol a polish, as well as a cleaner? So it will leave a protective barrier, which of course harpic won't? So not really a fair comparison?
I must admit I have used harpic on my Tiger. Triumph pipes are notorious for discolouring, and harpic restores them to their stainless state. But guess what, after rinsing and drying..... I then apply some autosolĀ
I certainly wouldn't risk not rinsing the harpic off!
So looks like you need a 5th pipe - Harpic + AutosolĀ :lol
