Yes, the DT does dry slower than most..
I have your health and safety in mind so there are no toxic dryers added.
Also, i am hoping to instill a slow build/ finish ethos as this will always give you a far superior end product.
Typically my scratch builds take three months minimum before i call them done. Most of this time is spent on the finish!
Because i am anally retentive about my finishes i leave each coat to dry for at least a week :)
