7 inch, Kompressorâ„¢ Foam Pads
Hats off to Lake Country Manufacturing. While other foam pad manufacturers struggle to keep their doors open, Lake Country has managed to pull another rabbit out of their magic hat. Just introduced at Automechanika in Frankfurt, Germany, the company's new Kompressor foam pads are being hailed as the most technologically advanced polishing pads in the world.
Kompressor - the next generation in foam pad technology
Two years ago, Lake Country Mfg. blitzkrieged the foam pad market when they introduced CCS Technology. Now they have raised the bar again with a revolutionary, patent pending, pad technology.
Each Kompressor pad starts as a block of foam that is contour cut on the top and bottom into a semi-arched shape. The pad face is then slotted in two directions while the foam is in this non-compressed, arched state.

A recessed opening is cut into the back of the pad to precisely center the backing plate. When attached to the backing plate, the pad flattens out, compressing the top surface and creating a dense working face ("Sweet Spot").
Advantages of Kompressor pads
The advantages of Kompressor pads will be immediately evident to everyone from the first-time user to the seasoned professional. These advantages are:
Slotted face constantly adjusts to surface contours
Extended pad life
Pad remains wetter, longer
Recessed back centers backing plate and prevents marring the finish
Perfect for newer, scratch-resistant clear coats
Larger "Sweet Spot" increases cutting speed
Less splatter
More usable surface area
Smoothest running pad ever
"Like floating on a cloud"
Pads are easy to clean
Here's a guide to help you select the correct pad for your needs:
7 inch, Kompressor, Purple, Compounding Pad - This is the most aggressive foam pad in the industry. In cutting power, it falls mid-way between yellow foam and wool pads yet it finishes like the orange and white foams.
Use this pad with compounds like Menzerna Intensive Polish to remove deeper scratches and severe oxidation that does not come out with the white pad.
Use this Purple Pad with caution. Compounding can dull the surface (called compounding haze) which will require additional finish polishing to remove. This purple foam pad is safe for use on clear coats especially when used with a dual-action polisher.
7 inch, Kompressor, White, Polishing Pad - The most often used pad. This pad has a mild cutting (cleaning) action and should be used to apply light compounds, polishes and one-step, cleaner/waxes. Use this Hi-Gloss White, Kompressor Pad with BLACKFIRE Gloss Enhancing Polish or Menzerna Final Polish II to maximize surface gloss.
This pad also works for applying one-step, polish/sealants like Klasse All-In-One and Autoglym Super Resin Polish.
Do not use the same pad for applying different products. If applying a polish and a cleaner/wax, use one pad to apply the polish and a separate pad to apply the cleaner/wax.
Note: Polishing pads can "cake-up" with residues reducing their effectiveness. If you don't want to stop in the middle of polishing to clean pads, plan on using 2 or 3 pads to polish the average car. Don't let polish residues dry in the pad. When you remove a dirty pad from your machine, immediately place it in a bucket of soapy (car wash shampoo) water or use a pad cleaner such as Snappy Clean Pad Cleaning Powder.
7 inch, Kompressor, Black, Glazing/Finessing Pad - This pad has very gentle cutting or cleaning action. It should be used to apply a glaze or a finessing polish.
Use this Hi-Gloss Black Glazing Pad to apply Menzerna Finishing Touch Glaze, 3M Imperial Hand Glaze, and Meguiar's No. 7 Show Car Glaze. You can also use this pad to apply Meguiar's No. 3 Machine Polish and 3M Finesse-It II Machine Polish.
7 inch, Kompressor, Red, Glazing/Finessing/Finishing Pad - This pad has almost no cutting or cleaning action but is a softer foam than the black pad. It should be used to apply a glaze or a finessing polish. Some detailers and body shops use both a machine polish and a glaze. Having two colors of glazing pads allows them to dedicate a specific color pad for a specific product to avoid cross contamination.
7 inch, Kompressor, Gold, Concours Finishing Pad - This super-soft pad is designed for applying the final wax or sealant to create the absolute best shine. This gold foam is forty percent softer than the red glazing/finessing foam listed above (100 pores per inch compared to 60 pores per inch for the red foam). The extra cell count means these gold pads disperse wax and sealants more evenly.
Backing Plates and Clean-up
These7 inch Kompressor pads have a 5-3/4 inch recessed opening which will fit our six inch, hook-and-loop, backing plate. Use our part number FBP-6DA for dual-action polishers like the Porter Cable 7424 and part number FBP-6C for circular machine polishers.
