I have
Meguiars #66 which I use on a
meguiars W8006 polishing pad by PC for very fast details, it also has a mild amount of cut to it too so I find it ideal for quick details and getting some paint protection too.
Also, Autoglym Super Resin polish is excellent when used on the PC I find - on a polishing pad, seems to take the product to a different level than when applied by hand and its also a one step cleaner/polish/filler/sealent. Ideal for a quickie.
