Need some help with my 1/32 Tamiya F-4J. I plan to leave the canopies on the open position. Now, here's the question: The canopy frames come molded in an inverted "V" shape that's open in the bottom Should these be filled with putty to "close" them in or be left "open"? Since this is going to be quite visible, I'd like to have it right. I guess since I spent so much cash on the kit, I can't afford to get any reference books!! Thanks for the help.
