These rubber eraser wheels are seriously effective for removing old decals, pinstripes, and stickers! You get two 4-inch wheels in the pack, each 25mm thick and made from durable rubber that won't damage your paint. They come with drill adapters that make installation super easy - just screw the adapter into the wheel and chuck it into your drill. The wheels can handle up to 4000 RPM, but you'll get the best results between 1500-3000 RPM. They work amazing on car paint, chrome, windows, and metal surfaces, quickly removing adhesive residue without harsh chemicals. Just apply gentle pressure and let the wheel do the work - it literally erases decals and stickers like magic. Important note: these aren't recommended for lacquer finishes, non-OEM surfaces, acrylic, soft plastic, or fiberglass. Always test a small area first, especially on older or light-colored finishes. The 250g weight gives them good substance without being too heavy for your drill. If you're tired of scraping for hours with plastic razors or using chemical removers that smell awful, these eraser wheels will save you so much time and effort. They make removing old registration stickers, dealer decals, pinstripes, or vinyl wraps so much easier and cleaner. Your arms will thank you from not having to scrape endlessly, and your surfaces will be left clean and ready for new decals or just looking fresh. Seriously, if you work on cars or just need to remove old adhesives, these rubber eraser wheels are an absolute game-changer that every DIYer should have in their toolbox!
