So I am going to be polishing my Silver Mercedes with my PC 7424 and Megs 105/205. My question is, is it even worth it to use a finishing glaze with the 7424 because of the lack of power? I thought I read that somewhere on here but wasnt sure.

You need more power with a compound than with a finishing glaze, so if it wouldn't be worth it to use a 7424 with a finishing glaze it sure wouldn't be worthing it using a 7424 with a compound if this logic were true.
The 7424 and all the rest of the first generation DA style polishers struggle at keeping larger pads rotating under pressure.
Paint is removed, that's another way of saying, defects are removed, when the pad is under pressure and rotating.
As pads become wet with product, the combination of wet foam acts to
absorb and dissipate the power coming out of the first generation DA Polishers, so you see this as a lack of rotating.
No rotating = no defect removal.
You could fix this with the older DA Polishers by either using smaller pads or switching to a dry pad after your current pad became wet with product.
If you in fact have a 7424, and not a 7424XP, (for some reason people don't ever type out the last two letters for the updated version so we don't really know which version you have and there's a big difference), then just stick with smaller pads, like the 5.5" Orange Light Cutting Pads.
These pads are thinner also and thinner pads rotate better and easier than thicker pads.
Be sure to carve out just a small section at a time when doing the correction steps.
If you haven't read through this, maybe give it a read-through as it's pretty thoroough...
