I used this alloy filler to repair a sizable chunk that had come off my BMW alloy. This was due to a repair shop hitting one of the spokes with a hammer when attempting to take a bolt off and then decided to use a wire brush to clean it and then spray paint it with a standard grey spray, so I thought I'd be better attempting the fix myself than leaving it with him. I couldn’t be more satisfied with this product. It applied smoothly, adhered well, and filled the area with ease. The consistency was just right, making the application process straightforward and stress-free. Once set, it sanded down cleanly and blended perfectly. This product worked exactly as expected—no surprises, just solid performance. Be sure to use plenty of masking tape when applying. £7 for a large 250ml sized tub is a bargain! Highly recommend. See my photos for the before and after pictures. Now I am just waiting for the colour matched paint. 5 star product. Review: Excellent filler, very easy to work with - I used this for a small automotive repair, and it worked perfectly. It mixes easily, spreads smoothly, and has a great working time before it starts to set. Once dry, it sands down to a very fine finish. It's a high-quality product that makes DIY repairs look professional. ## Features - Contains Aluminium Particles - Excellent Thermal Conductivity - Ultra Tough, Easy Sanding - Corrosion Resistant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00KX64QNI | | Blade Material | Metal | | Brand | SILVERHOOK | | Brand Name | SILVERHOOK | | Customer Reviews | 4.6 out of 5 stars 1,275 Reviews | | Global Trade Identification Number | 05036029110210 | | Handle Material | Metal | | Handle material | Metal | | Included Components | Applicator | | Item Type Name | Metal Filler | | Manufacturer | WEUANY | | Manufacturer Part Number | BIG21 | | Material | Metal | | Material Type | Metal | | Model Number | BIG21 | | Recommended Uses For Product | Automotive repairs, Construction, DIY repairs, Exterior surfaces | | Recommended uses for product | Automotive repairs, Construction, DIY repairs, Exterior surfaces | ## Product Details - **Brand:** SILVERHOOK - **Handle material:** Metal - **Manufacturer:** WEUANY - **Material:** Metal - **Recommended uses for product:** Automotive repairs, Construction, DIY repairs, Exterior surfaces ## Images ![Silverhook Big Boy - Relleno de Metal, 250 ml BIG21 - Image 1](https://m.media-amazon.com/images/I/81UoL8VGyiL.jpg) ![Silverhook Big Boy - Relleno de Metal, 250 ml BIG21 - Image 2](https://m.media-amazon.com/images/I/81URimuS8XL.jpg) ![Silverhook Big Boy - Relleno de Metal, 250 ml BIG21 - Image 3](https://m.media-amazon.com/images/I/81Jj+wkztjL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ The best alloy filler. 5 star product *by Q***N on 12 May 2025* This filler is the real deal.

It mixes easily, spreads smoothly, and has a great working time before it starts to set. Once dry, it sands down to a very fine finish. It's a high-quality product that makes DIY repairs look professional. ### ⭐⭐⭐⭐ Good filler, mixing is difficult *by R***M on 19 October 2025* This is a great product, does exactly what it says on the tin, fills, sands to a smooth finish and easy to use and mix, except, the instructions suggest mixing half the of hardener, which comes in a small squeezing tube with half the filler in the tin, problem is there is no way to measure with any accuracy half of either. So having prepared the surfaces to be filled I duly measured out what I considered half and half in a separate container and started filling, I worked quickly, however within five minutes it had set hard making the still to be used filler unusable. Being more careful with the other half mixing smaller quantities I managed to finish the work. It would be great if the manufacturer could provide some better means of measuring out ## Frequently Bought Together - Silverhook Big Boy Metal Filler, 250 ml BIG21 - SILVERHOOK Big Boy Aluminium Mesh 30 x 20 cm (12''x 8'') - Silverhook BIG11 Body Filler , 250-Millilitre, gray --- ## 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.fr/products/449386416-silverhook-big-boy-relleno-de-metal-250-ml-big21](https://www.desertcart.fr/products/449386416-silverhook-big-boy-relleno-de-metal-250-ml-big21) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-18*
