Currently i have the Meguairs g220 mk1 and the 4 pads that came with it. Currently on the lookout for some new ones, velcro backed so they can go straight on.
Looking at stuff from 3m, is there better stuff out there currently its about a tenner a go for a pad!

Im looking at a Flex DA but the price is so high. But id love to get a DA like yours or a Portercable and a Dodo juice spin doctor. There so meny combcs out there to pad to polish.

Could try some chemical guys hex logic pads if you haven't already. About £9 a pad but are very highly rated

sonus pads seem good

I went for the chemical guys fine pad and some 3m ultra fine perfect finish to do some switl removal

Also the late country house pad are quite good aswell
