Well, after reading the posts, I thought I would go out and purchase some Meguiars gear.
Got a Smokestone Saph that is looking a bit tired so I have bought the following and plan on using in this order.

Gold Class Shampoo
Scratch X (got the usual light scratches and blemishes)
DC1
Quik Clay
DC2
Gold Class Wax

Is this the right order?
Any tips on using any of the above would be greatly appreciated.
If done properly, how long do you reckon it should take from start to finish?
Would you recommend doing the polishing by hand or using my orbital polisher?

Thanks
Leigh
