Yes you are quite right but the resin used for boat making (Fiber glass) will shrink by 7% epoxy has polyurethane in it and will only shrink by about 0.2%. I'm not an expert in the subject of resins but be careful what you use when making coils it would be a real shame to spend hours getting a coil made up just to see it start to twist because of the wrong product used.

I should also mention that when I encapsulate my coils I do it in two steps, first I pour a layer in the mold let it set then place the coil on top of it and fill the rest, this allows the coil to be well centered in the molding and prevents over heating too.
