I wouldn't know. The Cabal was put out of its misery before I arrived
on the scene.

I just got a reply back form Franklin (real quick I must say). It seems
that the product is catalyzed with a compound which is acidic. IE - look
out bare metal.
However, that should make it bond to steel quite nicely.

I am up against a tight deadline here and not thinking well. You know,
measure twice and only cut once. The tip to rip off the screw up and reglue
is the right answer.

Many thanks.

As people said, it is water based. However, that water is acidic - fairly
strong - and it *will* eat steel. Removes rust too :)

The above applies to Titebond #2. Since #3 ate your steel I'm assuming it
is the same.

WHy izzit that this OP makes me want to scream at him?

"Well shiat, I put Diesel in my BiTurbo?"
"What On Earth should I do?" (Besides feeling that I should NOT own a
PM66?)

You glue on top of your PM66 and come in here to tell us about it???

As another author noted, the glue is water-based and water is
corrosive.

I think you would get a better match of the texture if you
use wood flour--sanding dust rather than sawdust. I also
think that if you mix your filler with whatever wood finish
you intend to use as your first coat (unless it is oil which
won't harden adequately) you'll get a better match in
color. Shellac is great for that sort of thing but you could
probably use varnish or lacquer too.

It's a water-based glue--I don't think it's particularly more corrosive
than an equivalent-sized drop of water would have been.

I'd probably be more inclined to cut a section off and reglue up a panel
than that, but depending on how visible the spot is a neat plug/spline
might be nearly invisible, too.

I hadn't looked at the MSDS or other data -- hadn't particularly noticed
the problem and I've done the same previously as well -- of course, the
top of my 66 is pretty well used by now so it isn't that shiny any more.

Glad the re-rip thought helped...sorry for the necessity.

Isn't there some type of appropriate punishment meted out by the Cabal for
this sort of thing?
