For a Porter Cable (and I`m assuming you meant 7424 and not 8424), you can do well with just a few basic pads. I like the CCS pads. You can use an orange for defect removal and black for applying your wax. A more aggressive approach would be a yellow pad for compounding, a white for polishing and then the black for applying your wax. (Note it`s not ideal to use a machine with a paste wax.)
Vibration and noise are similar (to me, at least) between the 7424 and the GG9. Both are nice machines.
Just remember to match your pad to the product being used - compounds/polishes get firmer pads, waxes get softer pads. Apply a small amount of product to the pad and set it on the paint surface, THEN turn it on. Start the machine at a low speed and gradually increase the speed. Let the weight of the machine do the work. Turn the machine off BEFORE lifting it from the surface. I generally work about a 2` x 2` area with compounds and polishes. Work overlapping passes several times, - up and down, then side to side.
It`s fine for curved surfaces, just remember to keep the machine moving.
What product were you going to use with the machine for removing the minor spiderwebbing you see in sunlight? Our 08612 Rubbing Compound and 08712 Finishing Polish used in tandem would do a nice job of making the surface flaw-free.
Good luck.
