3M Bondo All-Purpose Putty, Designed for Interior and Exterior Home Use, Paintable, Permanent, Non-Shrinking, 1.9 lb., 1-Quart

3M Bondo All-Purpose Putty is a versatile, two-part filler ideal for repairing a variety of surfaces like wood, metal, masonry, and drywall, offering fast, non-shrink, and water-resistant repairs. For best results, start with a small amount of hardener to avoid rapid curing, especially on hot days, and ensure the surface is clean and dry before application. Mix the putty and hardener thoroughly on a non-porous surface until uniform, then quickly apply using a putty knife or plastic spreader, working in layers for deep repairs if needed. Bondo becomes sandable in about 15 minutes, allowing for smooth finishing, but curing time may vary with temperature. Clean tools immediately with acetone and store the product in a cool, dry place with tightly sealed lids. With proper preparation and technique, Bondo delivers durable, professional-quality repairs for both interior and exterior projects.

Works great to repair old furniture

Good if you nneed something that sets up fast, but, be careful in warm climates, because it sets up too quickly for any kind of adjustment.

Worked great!

Bondo putty requires a little experimentation to get the hang of, but works incredibly well once you get used to it. The two part system and mixing in a hardener might seem like a hassle compared to one material putties and similar products. However, being able to choose the amount of hardener you mix in is a huge advantage. This lets you choose the "stiffness" of the putty - you can get from quite stiff (dryish peanut butter) to very liquid (Nutella-ish) depending on your application. This also affects the dry time - stiff mixtures harden very quickly (a couple min) - thinner, more liquid ones give you more time to work or allow doing multiple small jobs with the same batch. Clean-up is pretty easy and straightforward. The cured putty sands well (though does clog sandpaper - just hit it with a stiff brush to clear the putty dust out). It also takes paint well. Two coats and it looks fine. The tub here is also an incredible value - a little goes a long way, and this gives you plenty of material to mix many batches. It also lasts longer without drying out than some products you might use for similar applications like wood putty.

For those of you familiar with Bondo filler in any form, don't hesitate to use this product... you'll be happy to know it's like the good ol' product you're accustomed to. "Have at it", as they say. For those of you that are even moderately handy and can follow some basic directions, you'll also do well. Almost all the 1- to 3-star reviews are obviously from folks that mis-used the product. They're even a bit humorous and worth a read if you need a smile. My primary recent use has been to fill and fix rotted wood on the exterior of the house - primarily windows. Common sense will tell you to remove all the rotten wood first. If there is some wood that is still suspect, use a wood hardening product. When you're ready to use Bondo, know that while the product is fairly thick, it can flow a little until it sets, so you may need to form a "dam" of sorts to keep it from migrating for a few minutes. When mixing it, follow directions and scoop some out... don't mix it in the can! Also, don't overdo the hardener... and if your first batch still hardens too quick, reduce the amount of hardener used, per the instructions. It really is not hard to use as long as you have a bit of common sense and can read. Also, be confident that you will get better at using it as you go along! I've tried many wood fillers, and this is my go-to product. For finishing, I use relatively course files, shapers, and sandpaper to get it close to desired shape, and then finish it with 80-120 grit paper. Sand/shape at a moderate pace so as not to clog your paper or tools... this material is actually quite easy to sand and shape as long as you don't go crazy and sand too fast or use too fine a grit. Bottom line - buy it and use with confidence - the product is very capable of enabling you to restore your exterior wood pieces.

I used this to patch a large (4in diameter, 1.5 inch deep) hole in a table. It worked well, but I would say that it might have been better to do what the container suggested, and make multiple applications. Also, the smell is VERY strong, so windows open, and fans on, and probably use a respirator as well. A couple of days later, and the material still has a slight smell. Overall though, it got the job done.

I asked for it, because my dog has done some small damage in the house, when I received it and opened it I did not want to apply it because it had a strong smell of toxic and I was afraid that after the dog could lick and intoxicate, but secure it and work In this, the product dries instantly so you have to apply it immediately, the wood does not roll easily which means that we should sand a lot if we want a good result, but it did its job perfectly and deserved the 5 stars if it weren't for Its strong smell.
