Here's my experience:
I have some "1 hour" stuff. It's great for making thumb slugs. I guess it would also be good for quick repairs. It starts to set up about 2 minutes after mixing, is hard in about 15, and workable after an hour. Full cure is still 24 hours. Final quality is "acceptable", but far from "professional."
I also use the Ebonite everclear product. It's about 24 hours for cure, but I'm rarely in that much of a hurry. I like to give it a few days.
I've heard the thing about microwaving the mix, but haven't tried it - not sure I'd really want to try that. I've also heard you can use a space heater or even an ordinary lightbulb to help speed the curing process. And of course there's always the accelerator that comes with some of the plug.
Remember we are talking about a chemical reaction here, so you're pretty much limited by that. Sometimes a little extra heat can help the process, but no guarantee!
BTW- I'm not a certified driller, but I play one in my garage. jls would call me a hole puncher!
