I would swap out the PC 7424XP for the
Griot's Garage 6 inch Random Orbital Polisher, Dual action buffer, DA polisher. To me, the Griot's is the benchmark of the random orbital polishers. I've owned one for a two and a half years, and have yet to have any issue with it.
If you're looking for an easy to use kit, the
Meguiars DA Microfiber Correction System 5 Inch Starter Kit, paint correction kit, dual action polishing kit is a great kit and one that I own. It has everything you'll need to get a high shine finish without any guess work.
But, if you're wanting to buck the trend, then you have a vast variety of choices to select from. You have the Wolfgang twins as already mentioned. You can create a two step system from the
Menzerna line, depending on the condition of your pant. I'm not as experienced with their polishes as others, but forum member
BobbyG uses the line and uses
Menzerna Power Gloss, menzerna powergloss, menzerna S34A, menzerna s34, menzerna compound for compounding and
Menzerna Power Finish PO 203, one step polish, swirl remover, finishing polish, car polish, german car polish, menzerna polishing compounds, power for polishing. For an over the counter two step system,
Meguiars Ultimate Compound, polishing compound, rubbing compound, meguiars rubbing compound, meguires, meguiars polish, auto compound polish and
Meguiars Swirl X Swirl Remover, SwirlX, car polish, Meguiar's Swirl Remover, Meguiars polishes, meguires, megwires are the products that I used until the Microfiber kit came out, but I'll still go to them because I know they work. Selecting a polish can be overwhelming, given the amount of choices out there. But rest assured, almost any you choose will be great products.
If you decide to hand pick your polishes, you'll have to decide on pad choices. Just looking at the page can be overwhelming. So many lines, colors and sizes to choose from. As Mike Phillips would says "
KISS: Keep it Simple Simon". You were right when you wanted
5.5" pads. The smaller a pad on the dual action, the faster the results will come.
Lake Country Hydro-Tech 5 1/2 x 7/8 Inch Foam Pads 3 Pack - Your Choice! or
Lake Country Constant Pressure Technology 5.5 Inch Flat Pads, foam pads, buffing pads, sticking with Orange-Green-Black for the second one. Of course, getting 5.5" pads means switching out the backing plate with a 5" one.
Meguiars Mirror Glaze W67DA G110 DA Polisher 5 inch Backing Plate is the one I would reach for, and is the one that comes with the Microfiber kit I linked in the previous paragraph.
As previously answered, LSP=Last Step Product. It products all that hard work of polishing. If you're wanting a long lasting sealant,
Collinite Liquid Insulator Wax #845, liquid wax, heat-resistant wax, car wax ,
BLACKFIRE Wet Diamond All Finish Paint Protection, paint sealant, synthetic sealant, blackfire sealant and
We Are Car Care -- Car Wax, Car Polish, Auto Detailing Supplies, Car Buffers & Car Accessories Store excellent products, and are the three I grab the most when I'm looking for durability.
If you're wanting a beauty wax that you don't mind applying more often, then
DP Max Wax- Made with pure carnauba wax and advanced polymers. and
Pinnacle XMT 180 High Gloss Carnauba Paste Wax, XMT car wax, auto wax, best show car wax are quality choices.
