HEY JAMES,
It's been a while ,but I'm back. :yipee
On th Tamiya X-tra thin. It is a little similar to Tenax. IT works best if you can put th parts together & then hit it with th Tamiya thin. It's excellant stuff .I've been using it for a while now & before that I was using th Plastruct glue. IT's not as "Hot" as th Tenax but will still "weld" th parts together. The other Glue that Tamiya makes - The Orange cap is a lil' thicker & can be used as swiping a little on two separate parts & then putting them together - you get a longer working time with th Orange.
But given a choice , I'll take th Tamiya X-tra thin any day. It's very thin & will run into th joints very fast..... make sure you don't over do it as it's easy if it runs out, to get fingerprints on it. But these could be remedied but taking a little glue & going back over th piece to "erase" th fingerprints. Another cool thing that I like is th fact that th brush is in th cap !
Give th Tamiya thin a whirl .... I think You'll dig it. Save th Tenax for those Stubborn joints that refuse to stay glued !!
