Lots Of Review Confusion Here....
Reviewed in the United States on November 26, 2018

Amazon is obviously mixing multiple very different products here with the reviews. The product labeled Minwax High Performance Wood Filler is a great product for what it is designed. It is a two part system like Bondo and even dries grey. It does not come in a tube that can be already cut nor can it dry out. It is harder than wood and lasts years. I repaired my workbench with it then beat the crap out of it and it is still good several years later. Minwax High Performance is designed more for structural damage repair to wood that will be painted or nobody cares about cosmetics. It works excellent in repairing things like door strike plates that are destroyed or stripped out large screws/carriage bolts and knots that fall out etc. It is stronger than wood. Unlike Bondo it sticks to wood REAL good. Without all these bogus 1 star ratings from the wrong products Minwax High Performance Wood Filler would be a 5 star product as well it should.

Anyone who is still chasing a great "stainable" wood filler that will blend in and match your nice wood project might just as well shift over to Unicorns. The products are designed to work marginally on a real small finishing nail size hole. More like a brad.

Game changer if you like $ to stay in your wallet...
Reviewed in the United States on July 27, 2016

I have used this for many years... To fill in wood rot I have cut out. Before putting or replacing with this stuff - I put several screws into the remaining wood - which will be hidden by the wood filler... They serve as "anchors" to the wood filler. Amazing stuff... Have a sharp razor blade handy - and as the substance hardens - trim/cut the excess as close as you can to what you want the final surface area to be (starts to harden in about 3-5 minutes - then WATCH OUT - it hardens in about a minute). After it hardens - you can then sand it to smooth it out. This product has save me probably thousands of dollars over the past years in repairs to my wooden windows and surrounding trim... No matter how well I sand, scrub, prime and paint every few years - some spots suck up the moisture and you have soft wood rot... This product takes care of that. I have used the wood hardener in conjunction with this to harden the remaining wood - but only as a last resort as I attempt to cut ALL of the soft wood out. But - if that means you are left with nothing to anchor the screws with - then you need to use the minwax wood hardener (as directed) and wait the 3 to 4 hours for it to harden before adding the wood filler. But - I go ahead and drill starter holes for the screws and then screw in the screws (no all the way in, but far enough so they will not stick out of the final product you are looking for) before it hardens... enjoy

Excellent product, but directions are slightly inaccurate.
Reviewed in the United States on December 26, 2020

This filler is excellent. It dried and cured thoroughly, and seems to be as strong as others reported. The only reason it gets only 4 stars is because the directions misled me. The directions said to work quickly because trying starts at ten minutes after adding the hardener. I was pretty precise with the 1:16 ratio (hardener:filler), and I worked as quickly as possible, but this stuff started hardening after only about two minutes -- and it hardened fast. I had only done one of the four areas I had to fill (and I was filling gaps about 3/4" square), so I scooped the remainder into the trash while I could still get it out of the pan. I then simply ended up mixing three more small batches rather than a large one like the first. Though this worked, it was irritating -- besides adding work time, I had to smell the stuff longer than expected. I actually took a small break between each batch, because I had to get away from the work area for fresh air. DO NOT use this in a badly ventilated area. And if you later sand your work, also be in a ventilated area -- though the dust looks like regular fine sawdust, you'll smell the filler's chemicals again, albeit diminished. But despite all this unexpected irritation, I'm pleased with the final result.

Really great product
Reviewed in the United States on October 3, 2024

If I understand it correctly, this is a 2 part polyester based filler, very similar to auto-body filler. It adheres great to wood, it sands easily, and it sets up quickly. The only disadvantages are the fumes, that it can be a little difficult to get the ratio right, and that it sets up quickly especially in warm weather.

That said, I like it better than epoxy because epoxy is miserable to sand, takes forever to cure, and usually leaves a waxy film on the surface. Compared to drying solvent based one part filler, this cures faster and is a lot stronger. This is my go to for wood filler for painted anything.

Oh, and bonus feature, if you want a finer filler for after this for tiny defects, you can use auto glazing putting, like a 3m product. That will go right over this and make for a very smooth finish.

This stuff simply works
Reviewed in the United States on June 20, 2022

I was doing repair work on my front porch after removing bushes. There were areas that had rotted out due to weather. Each area was at least 2 inches by 6 inches. I first cleaned the areas of any remaining loose pieces. Then I applied Minwax hardener liberally to each area covering all exposed wood. I let this dry for at least 24 hours. I then used the minwax wood filler. I used a disposable/plastic scraper to mix the wood filler and supplied hardener. I used 1/4 inch hardener to a fold ball size filler. Once mixed well, I applied to fill the holes. I found it easy to apply and let it dry then add more until completely filled. I then let dry for a day and then sanded smooth to the surrounding area. Once primed and painted, it was like there was ever any damage.
I liked:
Ease of use
Quick dry
Harder than the wood
Able to sand with electric sander
Perfectly smooth
Once primed and painted, looks like never damaged and you can't tell repairs were performed.
Withstands weather so far

Overall a great product and recommend. There are other options out there. Some may work better for really large areas. The largest area I repaired was a 4 inch by 6 inch area. I filled the area in layers til done.

Product is as advertised. I have used this many times on MDF repairs and wood repairs. It is on the pricey side but well worth the expensive if you know how to work with it. My picture shows hidden trim damage inside a closet. Fabricated a form, filled it with the wood filler and as you can see from the results another successful project completed.

Excellent product.

Watch this video clip for great advice.

Weight the components! At a 16 to 1, to 20 to 1 ratio.

Work extremely quickly.

The trick in the video of using two paint scrapers is fantastic.

I was unaware or it, and it is better way to work with this product than mixing in a container.

Mix the can of resin well.

This is the best two part wood filler on the market. Period
When you need to fill large or small joints, voids, or feather out joints this is
bar none the best.
Why? because it sets up hard.
Now listen up, it's easy to sand.
Sets up hard and easy to sand for a joint fill that will not crack.
