Personaly I wouldn't use it. I don't like the double plunger thing for me it's actualy been less accurate than using a mixig cup. Unequal amounts of epoxy, mixed can be a real hassle Also 5 min epoxy set's real fast, it doesn't give you much working time, 15- 30 min epoxy would be better and stronger. Additionaly I've found the hobby brands to be of a better quality IMO

Can you use it, Yes.
Would I use it NO.
