I have not been able to permanently get rid of swirl marks using a PC. I can cover them up for a time, but they do come back. My experience has been that only a wet sanding followed by polishing with a rotary buffer will do the job. If you have had real success with the PC please tell me what you did. Thanks.

I have removed some pretty heavy defects with a rotary on a C5, it still will take some time.
The TR coupe started out like this:
As you can see the fwd part of the tape line was rotary polished with Menzerna PG, IP and FPII
The is the area to the right in the above pic after it was complete:

Even though motor power is not directly related to current on a single phase brush type motor, it is a pretty good indicator, and the PC 7424 and 7336 both have 3.7 amp draw motors which point to a motor that has at least 5X more power than the one you mentioned. It also oscillates with variable speeds up to 6000 OPM, producing almost twice as much "work" as the one you mention.
You will need something with the power (and pad availability) of the PC to get much work done on Corvette clear coat. I am assuming of course that you have a later model Vette with clear coat paint.

This was my first big-time turn-around.
1998 Grand Prix "Pace Car" with over 200k miles.
The picture below shows the roof panel. I ran a piece of tape from side to side on the roof panel.
The left side is polished with PB SSR 2.5 (x2) with the Orange Propel pad on my PC at 6. I removed the tape and took the picture below.
You can check out the whole detail HERE.

This can't hurt anything, and it may make applying wax or sealant a little easier than doing it by hand. But if you have any serious polishing to do, scratches, swirls, etc... you will probably need something like the Porter Cable.

Not only are you getting 5 times the power and up to twice the OPM, which as mentioned gives you 10x the power (well closer to 7 times) but you can also focus that power on a smaller pad such as a 6.5" or a 4". A ten inch pad has a surface area of 78.53981633974483 inches squared where as a 4" pad has a surface area of 12.5563 inches squared. As you can see, the 4 inch pad produces 4x's the working power of a 10 inch pad in terms of pressure applied, and can produce that pressure with out loading the motor as much.
