I use liquid hard wax which goes on like water an hardens not sure if it has carnauba in it it autoglym don't like to say
I use Meguires Gold class caranuba liquid wax and if applied with a damp aplicator sponge it mists up better so you can see where youve been but sets almost clear. (only dries with dust where you put too much on)
Ive never used Autoglym wax personally, but I used Simoniz Diamond Hard liquid wax that was a PITA to buff up afterwards! But gave a deep glossy shine.
