Yeah it is. I am very happy with the joints I have been getting with the T-88 epoxy from Rockler. I joined the top halves and the bottom halves with original Titebond and am not near as happy with those joints. They pulled apart just a tad at the ends. Of course I may not have done as good of job mating those pieces...but I went into the glue up thinking they were some of my best. The areas that well pulling apart were small and were cut away, but my joints with the epoxy have been great. In fact I had some drips on the back that I knocked off with a sharp chisel...and they pulled up wood anyway.
On a slightly different note, I forgot to mention that I was surprised at the porosity of the claro walnut. The epoxy squeezed all the way through 7/8" of top in 8 or 9 different spots right through the pores. I don't think that top is going anywhere.

Yeah I noticed that Claro does that also had the same thing happen with the peruvian walnut.
How are the glue lines with the T-88?
How is the mixing and cure time (I think Wes used it on one of his builds)?
The glue lines have been virtually non-existent on this one, at least on the fretboard and the top plate on the headstock. The top join appears to be the same, but it is only sanded to 60 grit so far, so we'll see how it cleans up later. The mixing is pretty cool. It turns a uniform milky white rather quickly and much more smoothly than any other epoxy I've used. It is very sticky and clingy when mixed and has a working time of at least an hour. It may be longer, I don't think it actually states it anywhere. It does say that it keeps on curing and getting stronger for several days. It claims to be a structural epoxy adhesive. it also claims to be good for oily tropical woods, like cocobolo. I've always left it overnight, clamped as hard as you would for titebond, and found it clear hard and cured in the morning, but I don't have a clue how long it took to set up.
Wes was saying in this thread that he was using it join a top plate on his tenia short scale build, but I don't think he ever made another comment about it.
