5インチ ソリッドPSA MIRKA BLUE AO ディスク 120グリット

Finally got around to swapping out my old discs for these, and the PSA backing grabs the pad perfectly—no slipping even on curved panels. They cut through primer and old paint fast without loading up, leaving a nice consistent scratch pattern.

Been using these 120-grit discs on my DA sander for a couple of weeks now, and they cut through paint and filler nicely without loading up too quickly. The PSA backing holds tight even on curved panels, which is a relief.

Peeled one off the liner and it grabbed the backing plate instantly, no sliding around even on a high-speed sander. The 120 grit cuts smooth and leaves a finish that needs almost no cleanup, so I’ve been burning through less paper than usual.
