Scott , are you sure the paper transfers a clear coat in its entirety to the substrate?
From what I have read and the vids etc I have seen it seems that its only the toner that transfers.
I could be wrong tho as I haven't done the process..if it is like that I would rethink getting into CLTT as I might as well just reverse print on clear vinyl and stick it on the substrate with a waterclear mounting film...
