Review: Used this to resurface my paper sharpening wheel works perfectly and it will probably last me a couple years easily. Review: I purchased this to apply to an MDF wheel mounted to a bench grinder for the purpose of sharpening knives. When applied to the MDF with white glue it chipped right off. When applied to the MDF with real wood glue it adhered very well. A light touch is all that is needed to produce a good edge. These two containers will surely last the average home shop enthusiast many years. ## Features - STAGE 2 OF 4 ROCK TUMBLING MEDIA GRIT - 2 pack of Stage 2 media grit for transforming rocks and gemstones into beautiful treasures.

Steps 3 and 4 will require 1 tablespoon per lb. of rock. **Q: Is this good for etching glass? Has anyone tried it on glass?** A: Yes, it will work for tumbling glass. Using Step 2 will give a matte finish. Tumbler for a couple of days and check if are happy with the finish. You may have to tumble a couple more days to get the effect you like. To get a more clear look, continue with Step 3 grit (500 grit) and then possibly on to Step 4 (aluminum oxide). **Q: Is it 6 table spoons of grit for 3 pouns of rock? The video doesn't show them putting that amount in** A: Yes. We recommend 2 tbs per lb of rock for steps 1 and 2. 1 tbs per lb of rock for step 3 and then 1.5 tbs per lb of rock for step 4. **Q: can this be used in a sandblaster?** A: YES ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***A on 25 March 2025* Used this to resurface my paper sharpening wheel works perfectly and it will probably last me a couple years easily. ### ⭐⭐⭐⭐⭐ Review *by J***. on 25 September 2023* I purchased this to apply to an MDF wheel mounted to a bench grinder for the purpose of sharpening knives.

It worked great. My only complaint is the consistency doesn’t seem as good as some other SiC powder I’ve purchased. It’s supposed to be 180/220 grit but seems finer at maybe 320-400 grit and there’s a lot of even finer dust in it. Still, it worked. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/256324926-rock-tumbler-media-grit-refill-2-lb-medium-180-220](https://www.desertcart.com.kw/products/256324926-rock-tumbler-media-grit-refill-2-lb-medium-180-220) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-15*
