I attended a workshop on working with composites at OSH one year. The first point they made was your immune system is like a bag you carry around with you. You do not know how big the bag is. Allergens accumulate in this bag. Once the bag is full of a certain allergen you will henceforth have an allergic response to it for the rest of your life.
When I was younger I did not have a histamine response to poison ivy... Now I do. I am a believer now.
In other words, we are all allergic to epoxy and poison ivy among many other things. The sooner you decide you want to start breaking out in hives from them the more you can expose yourself to them...
Needless to say, follow the instructions on the label to the letter or you will be sorry. (end of sermon)
