I've seen this discussed previously but cannot find the thread.  I've been using epoxy to repair cracks or minor inclusions in my pieces.  I like the Gorilla brand and have good success while I know others use CA glue.  Can I trouble anyone with a preference to respond with their pros/cons?

Thanks all...John

I don't have a preference, but I do think there are differences. 

CA, especially the thin variety, tends fill fine cracks better than epoxy.  I think the reason is that a high viscosity material won't flow into the crack, but rather will simply bridge the surface. 

But if the defect is larger, my experience is that a blend of epoxy and either sawdust or coffee grounds is more easily forced into the void. 

That said, I also have problems with air bubbles in epoxy (I suppose that's why they make pressure pots - but I don't have one).  But what I can do is fill the void, let it cure, cut back the surface, and then if there are bubbles, do another application of the filler.  Takes more time, but that's ok - it's not a race to the finish.

The other thing is that when mixing something like sawdust or coffee grounds to tint the infill, epoxy works better because you can blend whatever powder you are using into the epoxy before adding the hardener - which means that the time required to blend in the colorant doesn't subtract from the working time.  Just don't add the hardener until you have the colorant thoroughly blended into the epoxy.  If you are using CA, every minute spent blending the colorant is a minute less of working time.

And one other point - which also relates to the size defect you are working on.  CA tends to be brittle when it cures, while epoxy retains some flexibility.  If its a small crack, brittle isn't an issue, but it is if the defect is large.

I use both.  Another factor, epoxy is easier to sand.  I have been experimenting with white glue mixed with coffee grounds, seems similar to CA or epoxy, for large cracks.
