A new guy with a question. I’ve read about using bondo in woodworking before… this the same stuff used to repair cars or is there special wood bondo? Also, I guess you would apply it before turning? I could have searched for this but I needed one more post to get to five for sending p.m.’s…..thanks! Jim

Same stuff as used on cars. I use it all the time as a wood filler as well as for filling voids in cast iron and repairing dents on machine cabinets before painting – and all sorts of other stuff. It’s pretty versatile, and a can will last quite a long time.


PS: MinWax High Performance wood filler is just Bondo… but ccsts about three times as much.

Jim, Todd Clippinger talks about using bondo in this video. Not related to turning but may help.

I think a can of Bondo (from the auto parts dept.) is as essential to a handyman’s arsenal as a roll of duct tape….has a million uses.

I great stuff that has its place in the toolbox. Charles Neil introduced me to its uses in his period bed dvd. He used it to hold bed bolt in place to make assembly fool proof. It’s also used by antique restorers for moldings.

If you go to the Depot and look in the paint section you will find various wood fillers, one of them being bondo. I don’t think it’s any different than what you buy in the auto parts store. I always used to use the Durham’s water putty for filling rotted wood sills and things but it crumbles and cracks after a while.

Bondo makes wood filler, not sure would use this product or auto body bondo before turning! After turning that will be painted okay.

You do not want cracked/split wood coming apart as you turn. Getting anything used as filler can be iffy filling entire cracks & splits. Sometimes can get away with turn fill, wait for filler to cure and turn depending upon product used.

I have done this with regular carpenter’s & CA glue and saw dust, coffee grounds on small cracks.

If saw a picture of wood you are talking about might recommend throwing it away or send it out for stabilization or buy resin and do it yourself.

Wildwood, I really don’t have one particular piece of wood I’m talking about. I cut down a couple of pieces to get rid of a split or two, and it got me to thinking about the bondo. I can’t remember the name of it but I did get a can of stuff that mixes with water and is supposed to be for filling larger holes…at least that is what the label says. I may be old but this is a new game to me….LOL. Thanks again, Jim

Bondo is great for filling rotten wood sills,patching jigs that have been damaged,patching holes in woodworking.
The one thing you want to consider is that it does not accept finish. If it’s used on a finished piece you may have to break out your artist paint colors and try and match it that way. Another thing to consider is that bondo has 3 different hardner colors,red,blue,white,the white is much easier to cover than the other colors.I’ve only been able to find the white at auto paint suppliers.

A few years back I bought four surplus glass pane doors to close up an exterior entrance where a sliding glass door had been. The surplus doors had round holes for door handles cut into them. I used plain ole auto Bondo to fill the holes, over filling them a tad so I could sand them even with a belt sander. I painted the doors and you can’t even tell where the holes had been. This has held up perfectly for more than five years with exposure to the outside. Great stuff that Bondo!

I have not used bondo, I may give it a try myself. I have used sheet rock speckling as a filler for my kreg holes before though and it works great. Mostly in box bottoms and then cover with felt for a smooth bottom.

I used Bondo on a sailboat some years ago, and found that the difference in expansion and contraction between it and wood caused it to become loose and separate. Don’t think it was just water immersion cause it was not in the water that much.

bondo (the car stuff) is great for taking care of damage. As jim mentioned replacing rotten stuff.

But it also carves so you can repair damage from dogs chewing on table legs/carved feet.
