What epoxy hardener

[Jekyll]

I need to buy some new West epoxy and hardener for my windshield fairing and gear fairings. I used 205 hardener for everything in the past but, was thinking I might need 206 hardener for the windshild fairing.

What have others used for this?

I haven't done the windshield fairing yet, but I've done lots of other glass work on my RV so far with West Systems products, including making a one-piece canopy skirt. I use both. It depends on the temperature.

Here's West's chart:

I've found that when the temp gets beyond 80 degrees or so, 205 goes off too fast to use in anything other than tiny batches. If blending flox or micro above that temp, forget it. In fact I usually switch to 206 once it gets into the high 70's.

209 is the slowest (and best IMO).
