Here's a recent article I wrote based upon actually doing the thing I typed about.

Removing Orange Peel & Sanding Marks with the Griot's ROP and the Wolfgang Twins

Sanding marks can be removed using a DA Polisher but it's going to be harder with the model you have as it doesn't have the power to keep the pad ROTATING like all the new 2nd generation polisher have.

The new PC 7424XP, Meguiar's G110v2 and the Griot's Garage ROP all are dramatically better at keeping a pad rotating than the first generation DA Polishers and its' only when the pad is rotating on the surface that it is effectively removing paint.

Removing sanding marks means removing paint.

Your best bet would be with the smallest, flattest cutting pads you can get. 5.5 and even 4.0" spot repair pads are pretty easy to keep rotating.

Also, get an aggressive compound like the M105 and only work small sections at a time.

Then you have the new or 2nd generation Porter Cable Polisher.

If you look at the title you typed for your subject, you only typed 7424, not 7424XP

So my reference was in the context of the information you provided. I can't count how many people I interact with that have 7424 and 7336 models and I usually don't find out until I ask them directly because they don't include specific information in their writing.

Words mean things... and lack of words mean things too...

You will be able to remove sanding marks using a PC 7424XP but the right tool for the job is a rotary buffer.

One man's ceiling is another man's floor, what I mean by this is when removing sanding marks there's a difference between making the surface shiny and removing ALL the sanding marks.

Just a little buffing will restore a shine to the surface and some people may accept this. I'm usually held to much higher standards such as 100% defect removal. When aiming for 100% defect removal then for removing sanding marks, the best tool for the job is a rotary buffer.

Read through the links I've provided because in them you'll find the head knowledge you'll need to get the maximum performance from your PC as far as techniques goes, you will need an aggressive foam cutting pad and an aggressive compound.

Ah ok, i was looking at getting the lake country pack

Lake Country 5.5 Inch CCS Pads 6 Pack - Your Choice!

and the way i see it listed is the yellow is the heaviest cutting pad, along with the orange? I have a bottle of megs diamond cut #85 compound, not sure about the polish yet, i believe i have some 3m trizact 3000 still.
