The sponge body and abrasive grain are fully waterproof. Using them wet helps to carry away debris, keep the work surface cooler, and prevent loading – especially useful when color sanding automotive clear coats or polishing gelcoat.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pdd-faq-item\"\u003e\n\u003ch3 class=\"pdd-faq-question\"\u003e🔹 What’s the advantage of the sponge backing over regular paper discs?\u003c\/h3\u003e\n\u003cp class=\"pdd-faq-answer\"\u003eThe sponge layer acts as a cushion between the sander’s backing plate and the workpiece. This helps the abrasive conform to gentle curves and uneven surfaces, reducing the risk of cutting through edges, leaving flat spots, or creating deep swirl marks that are hard to remove later.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pdd-faq-item\"\u003e\n\u003ch3 class=\"pdd-faq-question\"\u003e🔹 Will these discs fit my random orbital sander?\u003c\/h3\u003e\n\u003cp class=\"pdd-faq-answer\"\u003eIf your machine accepts standard 4-inch (100mm) hook \u0026amp; loop backing pads, then yes. They are compatible with most popular brands like DeWalt, Makita, Bosch, and Milwaukee, as well as generic orbital sanders that use a 4” Velcro-style attachment system. Just confirm your pad size – it must be 4” in diameter.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pdd-faq-item\"\u003e\n\u003ch3 class=\"pdd-faq-question\"\u003e🔹 What grit should I start with for removing scratches before polishing?\u003c\/h3\u003e\n\u003cp class=\"pdd-faq-answer\"\u003eFor moderate clear-coat scratches, many detailers begin with #1000 or #1200 grit wet, then progress through #1500, #2000, and finish with #3000 before compounding. For deeper sanding marks or orange peel, you may need to start at #600 or #800. Always use the least aggressive grit that gets the job done, and follow a progressive sequence for a glossy, swirl‑free result.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cstyle\u003e\n    \/* ===== 唯一类名前缀：.pdd-wrap 避免污染主题样式 ===== *\/\n    .pdd-wrap {\n        width: 100%;\n        max-width: 100%;\n        margin: 0;\n        padding: 0;\n        box-sizing: border-box;\n        line-height: 1.6;\n        color: inherit;\n        \/* 继承主题文本颜色 *\/\n    }\n\n    .pdd-wrap *,\n    .pdd-wrap *::before,\n    .pdd-wrap *::after {\n        box-sizing: border-box;\n    }\n\n    \/* 标题样式：关键词自然嵌入 *\/\n    .pdd-heading {\n        font-size: 1.4em;\n        margin: 1.5em 0 0.8em 0;\n        padding: 0;\n        font-weight: 700;\n        line-height: 1.3;\n        color: inherit;\n        border-bottom: 2px solid #e0e0e0;\n        padding-bottom: 0.3em;\n    }\n\n    \/* 段落与文本 *\/\n    .pdd-text {\n        margin: 0 0 1.2em 0;\n        font-size: 1em;\n    }\n\n    \/* 特点列表 *\/\n    .pdd-feature-list {\n        list-style: none;\n        margin: 0 0 1.5em 0;\n        padding: 0;\n        display: flex;\n        flex-direction: column;\n        gap: 0.6em;\n    }\n\n    .pdd-feature-list li {\n        position: relative;\n        padding-left: 1.6em;\n        font-size: 1em;\n        line-height: 1.5;\n    }\n\n    .pdd-feature-list li::before {\n        content: \"✔️\";\n        position: absolute;\n        left: 0;\n        top: 0;\n        font-size: 0.9em;\n        color: #2e7d32;\n    }\n\n    \/* 表格容器：移动端横向滚动 *\/\n    .pdd-table-wrapper {\n        width: 100%;\n        overflow-x: auto;\n        -webkit-overflow-scrolling: touch;\n        margin-bottom: 1.5em;\n    }\n\n    .pdd-spec-table {\n        width: 100%;\n        border-collapse: collapse;\n        font-size: 0.95em;\n        min-width: 320px;\n    }\n\n    .pdd-spec-table td {\n        padding: 0.7em 0.8em;\n        border: 1px solid #d0d0d0;\n        vertical-align: top;\n        word-break: break-word;\n    }\n\n    .pdd-td-label {\n        font-weight: 600;\n        white-space: nowrap;\n        background-color: #f7f7f7;\n        width: 35%;\n    }\n\n    \/* FAQ样式：全部展开 *\/\n    .pdd-faq-item {\n        margin-bottom: 1.2em;\n    }\n\n    .pdd-faq-question {\n        font-size: 1.05em;\n        font-weight: 600;\n        margin: 0 0 0.3em 0;\n        padding: 0;\n        color: inherit;\n    }\n\n    .pdd-faq-answer {\n        margin: 0 0 0 0.5em;\n        font-size: 0.95em;\n        line-height: 1.5;\n    }\n\n    \/* 手机端微调 *\/\n    @media screen and (max-width: 480px) {\n        .pdd-heading {\n            font-size: 1.2em;\n            margin-top: 1.2em;\n        }\n\n        .pdd-spec-table td {\n            padding: 0.5em 0.5em;\n            font-size: 0.9em;\n        }\n\n        .pdd-td-label {\n            white-space: normal;\n            width: 40%;\n        }\n\n        .pdd-faq-question {\n            font-size: 1em;\n        }\n\n        .pdd-faq-answer {\n            margin-left: 0.2em;\n        }\n    }\n\u003c\/style\u003e","brand":"HomeDIYer","offers":[{"title":"300 -
