Never used such a band for modeling - only for boards of a bookshelf
I think it will depend on the location you want to use it - because the fixed glue (fixed at the veneerband) has to be fully heated by an iron, that it will really harden .
Using f.e. as a hull planking - you have to keep the plank correctly at the place and go over with the iron to fix it. So maybe problematic in the accuracy
I have my doubts, that it has advantages compared to wood glue and normal veneer
