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 - Causes damage to organs through prolonged or repeated exposure. - Causes serious eye irritation. - Causes skin irritation. - Flammable liquid and vapour. - Suspected of damaging fertility or the unborn child. - Contains Aluminium Particles - Excellent Thermal Conductivity - Ultra Tough, Easy Sanding - Corrosion Resistant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00KX64QNI | | Best Sellers Rank | 1,303 in Automotive ( See Top 100 in Automotive ) 16 in Fillers, Adhesives & Sealants | | Blade Material | Aluminium | | Brand | SILVERHOOK | | Customer Reviews | 4.6 out of 5 stars 1,343 Reviews | | Global Trade Identification Number | 05036029110210 | | Handle Material | Metal | | Handle material | Metal | | Included Components | Applicator | | Item Type Name | Metal Filler | | Manufacturer | Silverhook ltd | | Manufacturer Warranty Description | None. | | Material | Metal | | Model Number | BIG21 | | Part 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:** Silverhook ltd - **Material:** Metal - **Recommended uses for product:** Automotive repairs, Construction, DIY repairs, Exterior surfaces ## Images ![Silverhook Big Boy Metal Filler, 250ml - Image 1](https://m.media-amazon.com/images/I/81UoL8VGyiL.jpg) ![Silverhook Big Boy Metal Filler, 250ml - Image 2](https://m.media-amazon.com/images/I/81URimuS8XL.jpg) ![Silverhook Big Boy Metal Filler, 250ml - Image 3](https://m.media-amazon.com/images/I/81Jj+wkztjL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Hi, have a steel mount field lawnmower deck and have some holes appearing - would this be suitable?

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.nz/products/242007159-silverhook-big-boy-metal-filler-250ml](https://www.desertcart.nz/products/242007159-silverhook-big-boy-metal-filler-250ml) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-08-25*
