Which west systems kit?

[rodger.]

Was looking at the west systems kits.  Do you guys use 205?  Or 206?

I'm in Canada, so hot summers and cold winters.

Depends on your set time..  I usually use the 205 but, if I need a little more time then I use the 206.

I mostly use the 206 because I'm ordinarily using it with exotics and I want the slower cure. It works just as well with domestics, you just have to wait over night.

I think most people use 205.  I currently have System 3 Epoxy so I can't speak specifically about West Systems.  I'd suggest you start with the 205 - which is a faster hardener but has a lower temperature requirement.  It would be frustrating if your epoxy had issues because the temps were a little too low.   If it gets to be an issue in hotter months, use a different hardener.

Depends on what you are doing. If you are filling knots or cracks, then you want the fast one. If you are using it for a 20-30 min open time adhesive for tricky glue ups, you want the slow one. Which do you see yourself using west systems for? If you are split 50:50, i would get the slow hardener.

I use both. I normally do my glue ups and leave them overnight. Never had an issue with non cure when left a few hours. 206 is generally used on applications that need longer open times - complicated glueups in other words.

Thanks for the info guys, I am leaning towards the 205 (faster of the two).  Prob won't use it for full glueups very often.
