قرص نورتون توفباك PSA صلب أسود كربيد السيليكون

I was worried a P1500 grit would load up too fast on clear coat, but these silicon carbide discs cut clean and stay sharp way longer than the paper I was using before. The PSA backing sticks flat with no bubbles, which makes blending edges so much easier.

Used these P1500 discs to wet-sand the clear coat on a small repair and the finish came out glass smooth with no pigtails. The PSA backing sticks tight to my interface pad and peels off clean without leaving goo behind.

The black silicon carbide cuts clean and leaves a really uniform finish on my final sanding passes. I've used coarser discs that loaded up fast, but this fine grit held up through a whole batch of small parts.
