Are these sponge blocks compatible with my random orbital sander?\u003c\/div\u003e\n\u003cp class=\"spg-faq-answer\"\u003eYes — as long as your sander uses a 30mm x 180mm backing pad. The hook \u0026amp; loop (Velcro) backing grips firmly to standard orbital sander plates. If your sander accepts this size, simply press on, and you're ready to sand.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spg-faq-item\"\u003e\n\u003cdiv class=\"spg-faq-question\"\u003e2. Can I really use them for wet sanding? Won't the abrasive come off?\u003c\/div\u003e\n\u003cp class=\"spg-faq-answer\"\u003eAbsolutely. The sponge and abrasive are fully waterproof. Wet sanding is encouraged—it reduces clogging, keeps dust down, and gives a finer finish. After use, just rinse the block under water, squeeze gently, and air dry.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spg-faq-item\"\u003e\n\u003cdiv class=\"spg-faq-question\"\u003e3.

How long does each sponge block last compared to regular sandpaper?\u003c\/div\u003e\n\u003cp class=\"spg-faq-answer\"\u003eThanks to the open-coat abrasive and washable foam, they typically outlast traditional paper discs by 2–3 times, especially when used wet. Moderate pressure and occasional rinsing extend their life even further.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spg-faq-item\"\u003e\n\u003cdiv class=\"spg-faq-question\"\u003e5. Will these leave swirl marks on my car's paint?\u003c\/div\u003e\n\u003cp class=\"spg-faq-answer\"\u003eWhen you follow proper wet sanding technique with the fine grits (1500–3000), they create a uniform scratch pattern that is easily removed with a compound or polish. Used correctly, they minimize swirl marks and help you achieve a flat, glossy finish before cutting.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spg-faq-item\"\u003e\n\u003cdiv class=\"spg-faq-question\"\u003e6.
