Yes they are different...to be honest i feel that CG speedwipe is a dust attractant haha..i did a little test and put DG aquawax on my windshield..then a week later just cleaned it with speedwipe and literally 1 hour later it had a fine layer of dust on a not windy day. but i still love the stuff very much streak free. Last Touch has its place, cheap and can be cut 1:1 to cut down on streaking...but make no mistake, they are different products.
