Default Testors non-toxic cement for plastic models

Hello All,

The Testors non-toxic (tube-type) cement for plastic models (it comes in an "alicorn lightning pale blue" tube) came up in Reply #10 in *this* thread about the Estes Generic E2X bulk kit changes (see: http://www.oldrocketforum.com/showt...2903#post162903 ). I haven't used this cement myself, but I have been told by a local hobby shop owner that while it is lousy at bonding plastic, it is a good paper-to-paper and paper-to-wood cement. This got me ruminating on the following:

If this cement has physical characteristics (when dry) that are like those of the regular tube-type Testors cement for plastic models (and its equivalents made by other manufacturers), it might have several very convenient model rocketry applications (including in school and youth group model rocketry programs). These include:

[1] "Plastic sanding sealer & balsa wood grain filler"; The cement could be brushed (or "squeegeed," using a piece of scrap balsa) onto balsa fins and nose cones, being sanded smooth after the cement dried. This should also strengthen those parts as well as make their surfaces more dent-resistant.

[2] "Paper laminating glue for balsa fins"; White glue and yellow glue work well for cementing laminating paper to balsa fins, but these glues' moisture content can cause the paper to expand and bulge outward, creating little domes on the paper skins. If the Testors non-toxic cement for plastic models does not cause this problem with paper, it would be a good substitute for white and yellow glues for laminating fins. If so, the Testors cement could also be used to apply thin, moisture-resistant "film" coatings to parts of rockets (such as the lower ends of motor mount tubes, for example) that tend to get wet when flying on damp, grassy fields.

[3] This cement might be useful (particularly on small rockets) for balsa-to-paper joints such as balsa fins glued onto kraft paper body tubes, as well as paper-to-paper joints such as launch lugs glued onto body tubes. It might also work for gluing motor mounts and thrust rings into body tubes, although given the heat of the motor ejection charge it would probably be best to reserve these glue joints for white glue or yellow glue.

I hope this information will be helpful.
