Anyone ever use this stuff for Punky wood. I picked up a can this weekend and just now applied it to some really nicely spalted maple that maybe is/was a little too rotted.
It applies very thinly soaking up into the fibers and you then put subsequent coats on it that seem to fill in the punky fibers real nicely with a crystal clear coating.
I think it might be a good alternative to the super glue application.
Any experience with this stuff?

I've used the Minwax Wood Hardener quite a bit. It's probably the same stuff as the Bondo. It does penetrate deeply into soft/punky wood. I usually wipe a coat over the entire piece when done with the turning, so any finish will go on uniformly.

Haven't tried it but interested to know how it works. I deal with a fair amount of punky wood, sometimes on the edge of usability. It's a challenge to work with but I really like the result when it works out. I've been using JB Weld Wood restorer and like it but don't have any experience with other products. Running low so good to know before I get more.

Rather than pay the high prices for mostly solvent, I've been experimenting by thinning epoxy with acetone. Around 60% epoxy and 40% acetone. Been happy with the results so far on the half dozen or so bowls I've tried it on.

According to the SDS sheet it can be as low as 17% solids. So you are buying 83% solvents. Before things like Cactus Juice came out, a lot of pen turners melted plexiglass scraps in acetone. If you did that, at least you would have to add less coats as you could mix it to a higher percentage of solids. Not much different than Minwax based on percentages of solvent. https://multimedia.3m.com/mws/mediawebserver?mwsId=SSSSSuUn_zu8l00xM8tBO8mZOv70k17zHvu9lxtD7SSSSSS--

Thanks Tim for the money saving idea. I have plenty of both of those ingredients.
it is a bit pricey for what it is
