I have purchased two kits by trumpeter the osorio and k1a1 and the first went together no problems with good old testors,and the k1a1 I tried the same and it just keeps falling apart.I did purchase tenax but not sure on how to use it properly without melting the kit and or(sounds paraniod but those health warnings are not on there for nothing)So I am not sure on how to procede on finishing a nice kit and I have six of the newer ones on backorder,but won't help me if I cannot find the proper adhesive. So any help would be appreciated.
