I like the Super Resin Polish but no so keen on the Gloss, although other people have had greater results with the Gloss. Used together it does produce a glassy shine but goes after about 2 months (or 4 weeks in winter).
My choice is to use the resin and top with
Blitz wax, this gives a deep rich shine.
I cannot remember who did a direct comparison with
Klasse and said Autoglym had a slightly higher gloss but Klasse lasted longer.
Apply the polish in small amounts or it can be difficult to remove (but not that hard), leave for at least one hour and buff off. The Gloss is similar but if possible leave for 2 hours (one hour is enough).
I also like the glass cleaner and wheel cleaner but I no longer use the shampoo or rubber cleaners.
Give the stuff a try I think you will like it.
