I've pretty much reached the point when I can start assembly steps for F10. Added some PE bits on the weekend. Fujimi didn't pay much attention to insides of radiators, but I think they could be visible at right angle and under right light. I have 2 sets of PE from Studio27 and Hobby Design. Both have meshes for radiators. I've removed plastic tabs from insides and put Hobby Design PE there. Studio27 PE went to outside. Also used HD PE rings to simulate brake rotors. Haven't figured out how to apply minimum glue and still be able to slide then into place. So, got quite a bit of glue marks and CA glue fogging. I use Tamiya fine polishing compound to remove fogging and some marks.
