I think the best would be, if people could test it on another phone before disassembling their own phone. But that is of course not an option on Facebook… Do you link to the iFixit manuals when you suggest people to disassemble their phones? Maybe it takes away the fear, if they see what awaits them inside the FP2.
PS.: Maybe this photo helps too:
