Have you considered faux brick?? Seriously though, I have never had any problem just ironing it down. What does Faye Stilley say to do and who the heck is he anyway? Sorry if he is supposed to be someone famous, I just never heard of him. I'll try looking him up. How would ironing it down here differ from ironing it down on a solid fuselage? I am sure there are some who will say to use one of those "pecker wheels" but I have never used one of those either. I just start at one end and iron toward the far end. This doesn't give any bubbles a chance to form and it sticks just fine. Yes, I also use Monokote brand exclusively. Not saying anything bad about the others, just have not used them in 20+ years of flying.
Good luck.
