Testor's Plastic Cement Types TIPS
Here's the illustration used on Estes instructions to give guidance on what type of plastic adhesive to buy and assemble the kit.
It looks like the old tube style plastic cement I used as a kid.
Note the white oval on the upper right.
That oval implies "Testor's" brand available at Hobby Lobby and Michael's Crafts.
The red tube style (3501X) might be fine for plastic models that sit on the display shelf but not great for rocket models going through boost and recovery stresses.
George Gassaway used this "recommended red tube glue on his Little Joe II build shown on TRF. At ignition it didn't hold the launch lugs to the vacuform wrap. That led to a crash.
Stay away from the "Non Toxic" blue tube Testor's (3521X). We can thank the glue sniffer's for this useless glue.
Testor's also makes a bottled liquid glue (3502XT) that is probably okay for gluing the body details and tower assembly on the Little Joe II.
This is what you are looking for - Plastruct Plastic Weld Plastic Solvent.
George Gassaway mentioned in his build: "Tenax 7R also is good. Testor's liquid cement not as good but usable."
This is what I've used assembling plastic Saturn V and Mercury Redstone towers. Spray adhesive should be used for vacuform body wraps.
"Used for bonding Plastruct ABS, Styrene, Butyrate or Acrylic to each other, or in combination. Caution: Contains Trichloromethane. Do not take internally. Avoid eye contact and prolonged breathing of vapors. Use in well ventilated area. May cause nausea. Keep out of reach of children."
