you are again struggling with this damned putty that takes a loooog time to dry deeply ...well as Paul said , CA glue !!!!!!!!!!! , with a drop of accelerator ...........you will save time . I am amazed by such abyssal gap one a Fischer's kit
I think I have the putty problem under control, because of the size of the putty snake in the large gap I find the milliput needs a longer time to cure
If you expose the inside to air it seems to harden more, kinda like Tamiya putty which is why you layer it.
Good thing about it taking so long is that I was able to Plan more on the sequence I will put parts together.
I can see why there is this size gap, but it is not that bad really, and other parts seem to fit OK,
I've been using a lot of Milliput and CCA for my recent builds. Milliput dries rock hard in 24 hours. and I hate to be the barer of bad news, but if it hasn't already dried rock hard, most likely it won't. I've had this problem once before and found it was my mix of parts A&B. What I now do and it works 100% of the time, I cut a small amount from each tube and before doing anything else, I re-seal both tubes and back in the box they go. Then I roll each out into a string, the same thickness and cut the same length of A &B. Combine both together and then start rolling out a new ribbon. The key is equal amounts of both A&B and combining them completely together. Now apply, smooth out with a damp Q-Tip and let dry. Leave the un-used portion of the ribbon on your work bench as a control and it will harden in less then 24 hours and the filler on the model will be equally as hard.
I understand the mix and did this the same as you describe, but what I have found is after I let it set overnight and sand it down it is still soft in the center.
I left the sanded areas alone til this morning and they are hardened. I discovered that when I pulled the Milliput out of the spine on my F-105, that the next day it was hard,
I sand and let it set overnight and it seems to be working. I also made a control and when I dug into it is was softer but by the next day it hardened. Gave me a plan and
will continue to experiment.
Always learning something.
