Review: Good block - Solid block Review: Made a big difference when trying to get body filler flat - I am by no means a proffesional when it comes to body work and paint. I have been able to get almost professional results though. (apply paint, sand off, apply again until its good) When I used body filler I was getting low and high spots that were so subtle I couldn't detect them in primer and sometimes not even in the base coat. It wasn't until I applied clear that I saw them and sometimes not even right away. I discovered the term "block it out" and found out that my small sanding block and fine grit paper wasn't adequate. I bought the adhesive roll of sand paper in 80 grit. It turns out that really low grit (course) paper does a way better job of making a flat surface. Starting with fine grit will just keep the contour of the repair. They use this up and down/right and left and at diagonal angles as well. Keep the block in the same orientation and do the red lines on the British flag. In ASCII do the following patterns: / \ | -- Remember to keep the block in the same orientation. With this long and skinny block you are pulling and pushing the long edge at times. Then gradually lower the grit and continue using the block. Some people use a 'guide coat' of some type of spray paint that doesn't match the color of your body filler. When you sand it off you should see paint in the groves. (that way you know you still have sanding marks to get out) You should fully sand off the guide coat once you have it flat and smooth. Don't sand the surface finer than 600 grit. (you want maximum adhesion and primer/paint can easily fill in 600 grit sanding marks. It is hard rubber and doesn't give. You can probably find something flat to use instead but this works great if you are willing to spend a few bucks. The rolls of adhesive paper aren't terribly expensive when you consider that all sand paper is pretty expensive. (except those dollar store foam sanding blocks which work great on prep work and are grit - unknown) I did pick up sanding dust with my block before using the adhesive paper since it is so sticky it would be hard to get off otherwise. I watched a ton of videos and this brand seems to be popular with the group that knows what they are doing. I probably should have ordered the entire kit with several sizes and shapes of block. That seems like it is cheaper in the long run if you use the other sizes eventually. ## Features - Conforms to work surface - Follows curves or flat surfaces - Used worldwide, wherever professional body work is done - Uses 9" x 11" paper completely; No waste - 3/4" height x 1.375" width x 11" length ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0082LKFG8 | | Best Sellers Rank | #98,246 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #72 in Sanding Blocks | | Brand | Dura-Block | | Customer Reviews | 4.6 4.6 out of 5 stars (980) | | Date First Available | October 11, 2007 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.12 ounces | | Item model number | AF4400 | | Manufacturer | Dura-Block | | Manufacturer Part Number | AF4400 | | Model | AF4400 | | Product Dimensions | 11 x 1.38 x 0.75 inches | ## Images ![AF4400 Black Standard Sanding Block - Image 1](https://m.media-amazon.com/images/I/61I+VSZEHjL.jpg) ## Questions & Answers **Q: How does the sandpaper attach to the Dura-Block AF4400 Black Standard Sanding Block. Can a 9' x 11" sheet be used or do you have to buy the roll.** A: I used 9x11 sheets folded around the block, if you wet sand one sheet will last along time. **Q: Can you use sticky back velcro to use hook and loop?** A: I’ve converted all my blocks to hook and loop. Make sure they are cleaned with acetone or thinner real well, dry and them apply the loop side. A good panel adhesive or glue will help hold it even better than what comes on the hook and loop tape. **Q: Will this work to blend peeling clear coat?** A: For sharper curves and crevices with 7,000 grit wet/dry sand paper you could properly prep smaller area's of the surface for blending in clear coat. Be careful, you need a really light touch or you'll remove the paint. There are dozens of manufacturers of foam pads for polisher/sanders that are perfect for sanding polishing to perfection for blending top/clear coat. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good block *by M***E on October 31, 2025* Solid block ### ⭐⭐⭐⭐⭐ Made a big difference when trying to get body filler flat *by M***R on August 16, 2018* I am by no means a proffesional when it comes to body work and paint.

It is easy to use and can flex so that it can take curves as well as straights. I even used it to get that "hard to get" line on the vehicle door. It word very good. You can even get the larger one for longer straights like for the entire door but if you have a budget get this one as it can work anywhere on the car. I'm sure a longer Durablock can have a slight flex as well but this one did a fantastic job. I will also be ordering the longer one. ## Frequently Bought Together - Dura-Block AF4400 Black Standard Sanding Block - Dura-Block AF4405 Black Scruff Pad - Dura-Block AF4404 Black Round Sanding Block, 11" --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/17649194-af4400-black-standard-sanding-block](https://www.desertcart.com.ar/products/17649194-af4400-black-standard-sanding-block) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-08*
