    I got my daughter the Estes mix-n-match 60 kit for Christmas. Really cool and she digs the pink rocket. There are lots of plastic parts to glue to each other (nose cone and insert, motor can halfs, fins to motor can) then there is the the plastic motor can to paper body tubes. The instructions call to use tube type plastic cement at all interfaces. This is what I would have used decades ago in my youth but may not be the best choice. Seeing that I'm trying to take my builds to the next level and learn some new skills along the way figured I would ask type of glue would you recommend for these plastic parts?

    Use the recommended plastic cement?
    CA?
    Epoxy?

    Forgive my noob BAR questions as I'm learning to build better... Happy New Year!

    I used thick CA just cuz I had it. Epoxy can be messy and can trigger allergic reactions. Not the best with kids involved in the build.
    I don't doubt that plastic cement would work also.
    Yeah, 3 cool rockets for $16. Also picked up the Mix N Match 55. Great deals.

    Plastic cement is probably your best choice for these components. CA would probably also work, but I would stay away from the really thin (hot) types, especially around kids.. Epoxy may or may not work, as bonding to it is iffy depending on the type of plastic (plus the extra work).
    Plastic cement is solvent based and actually welds the pieces together.

    If the parts will glue with plastic cement, epoxy should work too. Plastics that don't glue well with epoxy include polyethylene, polypropylene, and Teflon; most plastic model kits are polystyrene. My personal preference would be to use the thin brush-on type of plastic cement for assembly, then use epoxy to glue plastic to cardboard.

    Just so ya know, asking a glue question on TRF will get you ALL the answers ! :)
    FWIW when the Estes instructions call out the tube glue hieroglyph I have used the red tube Testors plastic cement with 100% effectiveness.

    Meh, might as well throw this in since the thread is here:
    20191231_135322_HDR.jpg

    I like the Spider rocket.
    And you can get creative, it's Mix N Match, after all.
    I'm not, so I mostly followed the face card.

    BTW the recommended glue for the plastic fins to fin cans and plastic lugs to cardboard tubes on Aerotech kits is CA.
    FWIW.

    I use medium or thick CA on any of the Estes plastic attachment points.

    I have used with good success bonding other plastic parts to each other: Plastistruct Plasti-weld. with the orange label. it contains MEK so use in a well ventilated area and I would, at a minimum, supervise young children while this is being used. a little goes a long way. it will melt the plastic and actually weld the two parts together. a little drop brushed on will wick along the joint via capillary action.

    Deluxe Materials Plastic Kit Glue also does this. I used it on some plastic part from a Guillows airplane kit a little too generously once, lol.

    In all honestly, this is probably the most reliable way to glue the plastics together, as they actually kind of become one piece. That being said, I have never had the CA joints fail on these light rockets. I haven't tried that method on any of the PSII kits with plastic fins, though.

    I used the Plasti-Weld on my PSII Nike smoke fins and it bonded them together well enough to hold up fine on a few G64 and G79 flights. I would have no problem flying it on H motors except for the rest of the body sustained some damage on a hard landing. The fins were still fine though.

    A good plastic cement (Testors, Plasti-Weld) for the plastic-to-plastic joints (fin can parts together, nose cone caps on the nose cones).

    For plastic-to-paper I've used RC airplane canopy glue (such as Pacer Formula 560) for years, but just recently have been using Beacon Foam-Tac with good results (and faster cure times). Chris Michelsson has been recommending Beacon Fabri-Tac for these joints, but I had the Foam-Tac and it is working.

    Canopy glues are water clean up and don't have a strong odor, which is a plus.

    I have tried plastic cement (Testors in the black bottle) for plastic-to-paper joints (motor retainers on my Boosted Bertha) but those joints didn't hold. The parts got put back on the model with medium CA as a field repair. Those joints have been doing OK since then.

    Based on Chris's recommendation I would definitely go for the Fabri-Tac for the plastic-paper joints. It sounds really well suited for this purpose.

    The canopy glue idea is one I hadn't thought of. Beacon Foam-Tac is a personal favorite of mine. I use it a lot with foam airplane stuff. I also used it on my wraps on my Saturn V.

    Me, too. That's actually what I bought it for after reading about it somewhere online. And so far the wraps have been doing fine. It was WAY easier than trying to wrangle spray-on contact cement.

    I think you may have gotten that from me, lol. I had shared it here, and on facebook. Just an easy-to-use solution. It's holding up great on my Saturn V too. No lifting or anything. Seems to do the trick!

    Shared here, I may have seen it, yes. Great recommendation!

    I've been using Dap rapid fuse from home depot for the E2x kits. No idea if it's good or not, but it works well for the kids to build with, fast and not so messy, stinky, or instant stuck fingers. We did launch 4 kits built with it and no failures. DO NOT use the "non toxic" testors plastic cement, it just plain doesn't work.

    Well, the non toxic (blue label) Testors does work but it takes a long time to set up. Like overnight.
    So not good if you are looking at something to fly quickly. As in hours.
