      Well, I have now ruined 3 Zvezda kits by using Testors liquid plastic cement which tends to warp the plastic around the seams, especially the clear parts. Are they ( Zvezda) using a non-compatible formula in their plastic
      molding process ?? I notice their moldings are thinner and more flexible than I am accustomed to.

      I've used Testors on Zvezda kits and can't say I've noticed the issue you have described. Zvezda plastic is not as soft as Revell or Minicraft plastic. More similar to Airfix. That alone would suggest that your results with same amount of glue will differ. Fyi, Testors does make cement for clear parts only.

      I've quit using any liquid cement other than Tamiya Extra Thin. It's pretty "hot", but it takes such a minute amount to get a good join, I've never had any problems with it melting parts except when I've accidentally flooded it in (lesson learned - use a very small brush that doesn't hold very much).

      Thanks for the tip, Jennings ! I will switch to the thin stuff and a needle applicator.

      Nooooooooo! If you want to apply the runny cement, I'd suggest sticking with a small paint brush, (or an old ruling pen,) and take your time applying it. One over-squeeze of a needle applicator, and the stuff is all over the place, melting everything on the workbench! Hint: place the bottle in a weighted, empty can, to prevent spilling the jar. The last bottle of Testors liquid I used, contained methyl ethyl ketone, which dries slowly. (It's the stuff that was first used for plastic model kits in the '40s.) Most of the other liquid cements, including Ambroid and Weld-On, contain a large amount on methylene chloride in their recipes, which is very aggressive and evaporates quickly. I've used methylene chloride for years with very good results, plus, it's great for cementing ABS, styrene, polycarbonate, and acrylic.

      Absolutely do NOT use a needle applicator!! Use a VERY tiny brush and NOTHING else.

      I'm with Dana ^^. Been using methylene chloride for years. Great solvent.
      Definitely apply with a thin brush.

      Tamiya Extra Thin is awesome. Basically all I use now. Great stuff.
