40003 Wood Restore Repair Putty - 0.75 Pt. Putty, 0.75 Oz. Hardener

Excellent product two part product, puddy and hardner, worth every penny. Repaired a little rot in a exterior window pane, easy to mix, dries quick so work quickly. Dries rock hard. Easy to sand prior to painting.

Rarely does a product live up to its hype. This one does. It dries super fast. It is strong, easy to sand and paint, and is rock solid. I repaired a porch post that had a 6x1-inch deep rotted hole. Three-layered applications later, it looks as good or better than new and is stronger than the wood it replaced. I used to use Bondo, but no more! I love this stuff!

Yes, this expensive two-part filler adheres well and dries hard, but it's tricky to use as it dries VERY fast.

Well this product is essentially bondo. Mixes like bondo, spreads like bondo, smells like bondo, sands like bondo. It did a great job filling in some old beat up door jambs so that I could reset the latch catch. I would recommend the product and I'll definitely use it again.

Used this to fill in an area on a 4x4 post that had rotted out. Hole was about 3 x 4 inches and over an inch deep. It cures quickly so you have to work fast but that's what you want for vertical surfaces. A half hour later I sanded and primed it. Some paint and it looks brand new. A review here complained that the putty and hardener were the same color and you couldn't tell when it was mixed. The putty is light grey and the hardener is dark blue so it's easy to tell when it's mixed. J-B Weld products rock!

First time using this product. Used to fill gaps in cheap plywood before painting. Followed directions for mixing. Sets easily within 15 minutes and can be sanded soon thereafter. Would suggest mixing in small amounts till you gain experience with the amount of hardener needed. Very easy sanding. Used white primer to paint the filled edge. Filling not visible.

Sets up fast, which is good and bad. Goes from gooey to stiff so fast it's hard to use on vertical surfaces. Works best if you have several mixing boards so you can make several batches in succession and use small amounts at a time. Wish there was more hardner required so it was easier to tell when it was mixed

In a world where everything has been made cheap and disposable, this is one of those products that still performs extremely well, as a professional would expect. Of course, the cost is toxic fumes when the hardener is being mixed in, so wear proper safety gear and get the job done safe and right.
