Is this for you at all

Nothing stops you beginning
Two bottles, a cup, a stick and a mold. No license, no filed process, no inspection, and the materials are sold to anybody. Compared with an acidified food or a dairy product the barrier to a first piece is essentially zero, which is exactly why so many people start and why so many start badly.
The cost arrives later and it is paid in your body
Uncured epoxy is a sensitizer. Each exposure adds to the last, and once somebody becomes sensitized the reaction happens at doses that never bothered them before and it does not go away. People leave this craft not because it stopped paying but because they can no longer be in the room with the material.
Which inverts how you should think about protection
In a food craft, care protects the customer and sloppiness shows up as a complaint. Here care protects you and sloppiness shows up as nothing at all, for a long time, and then as a career ending. There is no feedback telling you it is going wrong, which is the whole problem.
The finished piece is inert
Fully cured resin is a stable solid and is not the hazard. That is worth being clear about because it is the part buyers ask about, and the honest answer is that the risk sits entirely with the person who mixed it, in the minutes before it set.
Who it suits
Somebody who will read a safety data sheet, buy the right gloves rather than the convenient ones, and ventilate properly on the first piece rather than the hundredth. The craft rewards patience and punishes improvisation more than its reputation suggests.
What this property covers
The chemistry that produces the heat, the exposure that accumulates, the two labeling regimes you might fall under, and the container decisions. It does not teach you to cast, which is learned by casting.
