Bondo Rotted Wood Restorer, 8 fl oz., Penetrates into Spongy, Dry-rotted Wood Fibers Creating a Solid Surface, Dries clear and tack free, Water Resistant, Stainable and paintable (20131)

I used this material to repair dry rotted wood around the exterior refrigerator opening of my travel trailer. The product worked exceptionally well.Thanks to the RV manufacturing crew in Elkhart, Indiana who failed to use a putty or caulk to seal the exterior plastic weather frame around my refrigerator, water continually leaked in around the frame and rotted the wooden lower half of the exterior box of my refrigerator. Discovered years later. What a mess.After days of work to remove the soft rot and weeks to allow for drying of the remaining wetted wood, I used this product to treat and seal the wood up. It worked well. It hardened the formerly wet but solid remaining wood. Like, rock hard solid. Provided a shiny coat. To replace the missing soft wood removed on the frame, I used regular Bondo wood filler. Sanded it, then sealed the repaired areas with a tube of waterproofing 100% silicone caulk, and caulked the plastic weather frame (unlike the crew who built my RV who skipped over that important detail, not to mention puncturing the weather seal near the refrigerator with unsealed screws... so much for Made in the USA American craftsmanship on this job, that's the kind of stuff that damages our reputation).Strong chemical odor when wet, would not want to use this material in an enclosed air space without a respirator. Highly flammable when wet. No open flames nearby with this stuff. Since an RV has a gas refrigerator with a pilot light, and has electrical wiring on top of that (not to mention the water heater was below the refrigerator), all propane lines need to be depressurized with DC and AC electrical turned off in that area to avoid any static sparking mishaps. Put the Dremmel away. I kept a fire extinguisher nearby just in case something went wrong. All my work was done in an outdoor setting.Some drops of the product landed on the RV bumper and dried (it's as thin as alcohol). Shiny, clear, and cannot be removed. Be careful of it splashing or dripping on other materials. Wear old clothes that don't carry static electricity.So my recommendation on this product as a rotted wood hardener is strong. It works. Glad my high-skilled carpenter neighbor recommended it. When used with regular Bondo wood filler, it solved my RV refrigerator frame box rot problem.

We had a small spot in our motorhome with the wood seem to be giving underneath our feet so we removed the vinyl flooring and cut away all the rotted wood. When we costed it with this product and was very pleased with the results. It’s very easy to apply, very inexpensive and it dries quickly. It works very well, but it does have a rather pungent smell, and we had to open the doors and windows and put a fan on to blow the scent out of the motorhome. All in all we’re very pleased and would recommend it to others

Have been using the product for years with good results. Satisfied with the product. Would be nice if the container came more than 2/3 full like mine was. Maybe there’s a good reason for this? Room for expansion? Also, they used to include directions on the can. Now they want you to scan a QR code for directions. Inconvenient.

It does hardened soften wood. I think mine was a little too far gone but the remaining that I could coat got rock solid by the next day. I used wood putty to fill the voids.

Does what it says. Really hardens rotten wood.

Don't get this on anything you want to keep nice. Don't get it on paint. It will bubble it right off

Easy to apply with the built-in brush. Takes a while to apply over a large area--multiple cans probably needed. Strong odor when applied.

would buy again
