i sell the stuff and althouh autoglym is good meguias is so much better.
the equivalent to super resin will be cleaner wax.very fine cutting agent in a protective wax. for best results the clay to start,cleaner wax,step 2 deep crystal polish(which deepens the paint colour.) then nxt gen tech wax.
if using the clay make sure iti isnt a old day. you have to make sure he clay can stay supple or you could scratch paint.warmish days stop this.

with nxt gen tech wax 2 thin coats are better than 1 thick coat.
hope this helps
