Will do. I just recalled now that you mentioned struggling a bit with realistic welds and needing quite a few for my abrams, I did as well. There's a modeler on YouTube
https://www.youtube.com/watch?v=F3GlNC2cK8s showing great results using epoxy putty but being the slightly lazy type I wanted a easier option . I'd had some luck with squadron green putty rolled out into a thin snake , the advantage being in my mind , it's solvent based so I could attach it and smooth in place using liquid cement and even the fact that it shrinks while drying seems a benefit. Disadvantage being it dries out and becomes crumbly quite quickly (especially in small amounts) and limitations in the length that can be prepared before this starts to happen.
I had tried a syringe type setup but thinning the putty enough to flow through the syringe made it too thin to be workable. After some thought I figured out I shouldn't be trying to apply directly to the model with a long and thin tip to reach in corners but simply extrude a nice consistent bead on my worktable , then cut into sections and apply where needed. I made up a little extrusion nozzle from brass rod with as small a hole as I could manage (.008") that's threaded to screw right onto the tip of a disposable plastic syringe. The putty doesn't affect the brass of course and apparently the plastic of the syringe either.
Being that you're working in twice the scale I am and that being a functional model would need to be more robust the squadron putty might not be the best choice but maybe something along those lines ?
