Best Body Repair Putty of 2026

"I was blown away by how simple it was to use this epoxy putty. I fixed a large rust hole in my patio table that sits by a saltwater pool, and the repair turned out rock-solid and nearly invisible after painting. This product held up great even with kids constantly using the table, and it definitely saved me from buying a whole new set. Highly recommended for tough, rust-damaged metal repairs!"

"I bought this after researching how to fix a broken chair and wondering if I’d need to have it welded. J-B Weld did the trick perfectly—it was clean, quick to apply, and hardened completely in about 15 minutes. The chair feels sturdy and reliable now. Just make sure you check the load requirements for your own project."

"I needed to fill a hole in some bent metal, and this product was exactly what I was looking for. Super easy to use—just knead, apply, and let it cure. I left it overnight and painted over it the next day, and the result was fantastic. Would absolutely buy again."

"I was really impressed with how hard this product cures and how well it bonds to plastic. I used it to fix my car’s wind deflector, and after sanding and painting, I honestly can’t distinguish the repair from the original. While it’s a bit pricey for the amount, it absolutely did the job I needed."

"I used this on my microwave handle after scraping off the old adhesive, and now the handle feels like it’s cemented on for good. This stuff really exceeded my expectations—I couldn’t be happier with how solid the bond is."

"I had a failed 3D print that I needed to repair, and this product was perfect for creating a strong bond even over a small contact area. It gave me ample time to work with, was shapeable, and the end result is surprisingly strong. It did start to set a bit faster than I hoped, but compared to alternatives, it’s still my top choice."

"As a first-time user, I found this product extremely easy to work with and it mixed well. It held securely, took paint beautifully, and I'm very satisfied with the final results."

"I used this filler for my car body repair and honestly, it's one of the best products I've tried so far. The only thing I'd caution is to use proper protection gear due to the smell, but it performed flawlessly for the job and I would recommend it."

"The product does exactly what it should, but watch out for the instructions—they're not very clear. I had to look up mixing tips online. Once I got the proportions right, it worked great—hard as concrete and filled my wood door holes perfectly. Just be prepared for a very strong smell and work in a ventilated area."

"I used this product to bond rocks and wood in my aquarium and was impressed by how strong and secure the hold felt. I trusted it enough to put it in with my fish. The only tricky part was getting it off my gloves and it does leave noticeable residue, but overall, the result was solid and reliable."

"As someone who refurbishes cast iron, I tried this on a severely cracked antique kettle. The putty was easy to work with, filled the crack perfectly, and sealed so well I could fill the pot with water and it didn’t leak at all. I’ll definitely use it again for future projects and recommend it for repairs or repurposing where strength matters. Just remember, it dries white so you might want to paint over it."

"I had a leak in a PVC pipe and after other products failed, I gave this a shot. I followed the instructions and the repair held up beautifully under water pressure. Now I always keep a tube around for emergencies, because it’s reliable and effective, especially for quick fixes."

"I've kept a can of this product in my workshop for years and have used it for everything from auto repairs to fixing damaged wood and plastic. It outperforms superglue, is easy to shape and sand, and blends seamlessly with painted surfaces. The repairs have held up in the tough Wisconsin weather. My only tip: you'll need a pilot hole if you want to screw or nail into it."

"As someone who often flips furniture, I swear by this product. It never shrinks while drying, leaves a smooth surface ready for paint, and saves me a lot of time because of its minimal dry time. The only thing to watch out for is the strong smell, so make sure to work in a well-ventilated area."

"I recently tried this filler for the first time on a plastic bumper hole and was amazed by how quickly and solidly it hardened. The clear instructions made mixing easy, and a little bit went a long way. Great value for the amount you get. In the future, I’ll mix small batches since it dries fast!"

"I found these really easy to use and clean, and the thickness was just what I needed. They've been a handy item to keep around for various projects."

"When gluing puzzles, these spreaders make it simple to apply glue evenly and even help get it between the pieces. I also end up using a lot less glue overall."

"I appreciate that the pack comes with three different sizes. The spreaders have the right amount of flexibility, and the handles are well-shaped for detailed work."

"This is my go-to Bondo for strength, much sturdier than the standard version. The only catch is that it dries super fast, so you have to be quick and precise with application, but the results are worth it."

"I'm pleased with how quickly this product cures and how smoothly it sands down. However, I wish it gave me a bit more working time. Next time, I'd look for one from the same brand that hardens a bit slower."

"While the Bondo-Glass is highly rated and offers solid performance, I honestly found it a bit pricey and not as impressive as I hoped. For future repairs, I'll likely go with another brand, but it did get the job done."

"I’ve tried a lot of products, but this one stands out as the best purchase I’ve made in 2025. It’s not a typical wood filler—it’s perfect for smoothing out wood and filling pinholes or grain. Dries super fast and sands to an unbelievably smooth finish. While it took some time and was a bit messy using it on a full door, the end result is so smooth I can’t stop touching it. It’s not the easiest product, but the results are amazing."

"Whenever I refinish furniture, I reach for this. It dries quickly, is easy to sand, and leaves a hard, durable finish. It’s become an essential part of my process."

"I use this for repairing and finishing 3D printed models, especially with PETG. It mixes well with acetone for brush-on application, dries fast, and sands easily. The tube packaging is convenient for using small amounts at a time, which means less waste. It’s my go-to for smoothing and priming prints."

"As someone who does plenty of 3D printing, I found this product to be a huge time and money saver. One tube has lasted me through over a hundred prints. The quality is fantastic, and it sands down super easily. The only downside is the strong smell, but that’s typical for Bondo. Just make sure to use it in a well-ventilated area and wear a mask if you can."

"When working on cabinets and wood projects, this has become my go-to filler. It outperforms traditional wood filler, is simple to sand, dries quickly, and makes the surface smooth for painting. It’s also easy to clean up—I couldn’t ask for more!"

"I use this to fill in the print lines on my cosplay pieces, and it’s what everyone in the community recommends. Sometimes it dries a bit too fast straight from the tube, but when it works, it’s incredibly sandable and does a great job hiding layer lines. I’ll definitely give it another try to see if the drying issue was just a fluke."

"This kit was a lifesaver! Filling in those little scratches on my car was super simple, and after sanding them down, I had it vinyl wrapped—you’d never guess there were even scratches there. It worked amazingly well!"

"I used this on my Boba Fett helmet project and needed less than a quarter of the tube. The filler dried really fast and sanded smoothly with the included sandpaper. My helmet’s ready to paint and I’m definitely happy with how it turned out."

"I scraped my truck on a gate and this kit made repairs easy and straightforward. The only thing was the sandpaper started to clump quickly, so I switched to a heavier grit I had on hand. Still, it got the job done."
