Working on the dreaded 1/48 kitech SU-35...I got everything pretty good except the canoy & W/S. Major gaps there. Found at the last moment..To fill the gaps I've been using future a little at a time...not quite done yet ...but I think it will work out
I let it thicken up a bit for a few days before I applied it. The thickened Future flows into the gaps ok... just used a toothpick .. a few more apps and it should seal it good enough...so to speak.
