Polishing for Aerospace Finishes
Mirka rotary, orbital and cordless polishers, Polarshine compounds from coarse cut to finishing wax, and the foam, wool and felt pads that go with them. Pick the polisher, then match the compound and pad to the finish you need.
Engine Inlet Cowl Polishing: 36 Hours Down to an Estimated 8
A long grit progression plus oil and paste became a shorter Mirka sequence: sand 240 through 4000, polish with a yellow wool pad, finish with Polarshine 10. The customer saves time and labor with a better finished appearance.

Foam, Wool and Felt Pads, Matched to the Compound
Waffle foam by color: yellow for medium cut, orange for soft clear coats, black for hologram removal, burgundy for hard coatings. Twisted wool and lambswool for the coarser compounds, white felt for glass. Each card lists the Polarshine grades Mirka pairs it with.
Backup Pads for Each Polisher
Grip backup pads sized to the POLAROS and the 3" pneumatic polishers, plus a 7.875" pad for buffing. The 3" pads ship as the standard pad on the MROP-312TH, MRAP-30 and MR-30.
