3M Bondo Wood Filler – 30 fl oz, High-Performance Two-Part Formula for Interior and Exterior Wood Repairs, Fast-Curing, Paintable, Stainable

Used this to help in fixing some rot around a porch door. Worked like a champ! Cut away the portion that needed to be repaired and fitted some wood pieces to primarily fill the void. Used this wood filler first, against the existing wood that remained, then put in the wood pieces I'd prepared. Secured them in place and then let the filler cure - maybe about 30 min or so. Mixed up another, smaller batch of the wood filler (mixed as directed) and used it to fill in the gaps. Once cured, sanded to a good finish, painted and it all came out pretty good. Not perfect - but that's because I'm not a builder but it certainly worked and helped with this project. I wanted to use this one since it's an exterior door and I wanted it to be weather tight. All good

This stuff is amazing. turns rock hard easy to manipulate fast acting

I used this almost every day for my furniture projects. It's quality, it's dependable, easy to work with and dries fast. Only thing I wished they do it change the color. I wished there was a wood color, or at least something of a neutral tone. Maybe there is and I haven't looked hard enough? But as long as this product still exists, I'll still be buying it!

Easy to mix and apply. Very fast set, so must apply quickly. Easy to sand to a smooth surface. Mixed color is light green with supplied hardener, so must use an opaque stain or paint. Very effective when used over rotted wood restorer.

This stuff works great for repairing damaged wood.

If you don't mix the creme hardener in thoroughly the product won't get hard. It doesn't take much of it but you must be thorough. When mixed properly this is my favorite go to for filling places with rotted wood that don't need completely replaced. It hardens in under and hour and can be sanded easily and once it's painted it looks no different than if you had replaced the entire piece of wood. I have excluded pics of how I used it to make a repair at the bottom of a section Of my porch. Once I cut out the rotten wood, I used the bondo wood filler to fill in the bottom. I did uses a small piece of wood that was not as thick as the surrounding wood and used the bondo to fill in and smooth out the rest. After sanding and painting, it looks like I replaced the whole piece. Great stuff. Just make sure you mix that creme Hardener in all the way or it stays gummy and you'll have to scrape it off and try again

worked well, adds rigidity and strength.

Used this to fill old deck boards while remodeling our deck and worked fast and looks great.
