Thank you all for the help
I'm now narrowing down the yellow-green as suggested or the silver-grey, since I want this kit completed and 100% ok I think I'll go with standard for now and test out the silver-grey sometime later, will grab some of the miliput next week at the LHS and give it a shot.
It seems from reading your advice milliput is very similar to clay and thankfully last year I did a clay class in my college, was a wonderful experience and we got to make some lovely things, I especially enjoyed the eagle mask and shark serving tray
I'll get some pics up later if you guys like.
As for your advice Walrus,
I'll follow it for the future and see how it goes, so far for this kit i need a 99% good to go solution so will try the miliputt hehe
CA and talc i've tried but its been very touchy and smelly and anything that has a funky odor is a no go as my workbench is fairly close to the neighbors and opening a window would karate chop them into smellyness lol
I'll be using the milliput to fill seams (usually small ones as I work from 1/144 up to 1/48 so they aren't large), the fuselage seam is fingernail length/possibly smaller that I was filling, it is a 1/144 kit I've been working at for 3-4 years already and preparing her for our IPMS competition.
I used the Tamiya white putty in a thin application and then sanded, but it appears that I've had a bad batch as it has shrunk over time, the kit was painted and ready to go but I noticed that it developed a seam, so it was back to the drawing board and asking the forum for help. If it wasn't for competition I wouldn't mind, but I've cut the kit fuselage apart and scratch built a radar installation so I like it to be done right with all the work involved.
Funny enough I went to my other models and checked them for seams (the completed and non-completed ones) the ones I did with the Tamiya Light Curing putty = no seem, each kit I've done with the Tamiya White putty = seam :O so I've got a couple to fix.
I'd like a ready made solution and as mentioned Bondo 801 (the one most recommended on the forums) is unavailable here, most two parts aren't supposed to shrink, so I think for the safety aspect of this build I will go with the two part for now.
Thank you all for your help and guidance on this
I went from nightmare :..( to "it will be fixed!"
