OK, thanks. How long does it take to cure, and how much does it smell?

It curse over night depending on the weather. It does tack up and get thick in about 15 to 30 minutes. When I made up the cowls it was pretty cold out so I had a lot more work time then normal. Mix up a small batch and see how much work time you are getting and how long to get a full cure. That way you will have an idea of how big an area you can do at a time Before it starts to thicken up.

There is negligible odor from epoxy.

AS GB says, it will set up overnight. This process takes some time, but is worth the effort.

I used some 30 minute epoxy yesterday late afternoon, about 3 or 4? It finally set up in the mixing cup about 8 or 9. It was just the motor mount on my electric but I waited until this morning before I tried mounting the motor back on so I wouldn't tear the mount off by screwing the motor back on. The Zpoxy is a slower curing type. It sets up over night and you can work with it but if you let it cure for a couple days it sands better. If you have never worked with it before you really should do some testing so you get the working time figured out.

Hi!
Get professional 24 hour epoxy instead! EMC-Vega has a good epoxy . It gets glass hard after 24-30 hours and is easy to sand and it doesn't smell at all.
The "Hobby type" epoxies are not that good when it comes to cover a model with glass fiber.

I finished my tested with this cloth I picked up at a fabric store. It shrinks quite well with a touch of the heat gun. Looks like it will work fine for dope covering, but not resin covering.  I got that 20 yard roll of .56 fiberglass last week, so only thing I need now is more resin and some dope.
