    I just bought Astrotrain and Scourge, but they are both super floppy. Scourge's "underbelly" panels in vehicle mode won't stay and are hanging loose, and Astrotrain's left knee is flopping all about. I usually use Pledge floor polish to tighten ball joints, but I don't know what to do for pins. Thanks!

    Loose pins are tough. Only two solution come to mind:

    1. If you can pop the pin out, coat it in floor polish. If it's not that loose, try dropping some floor polish into the pin hole, and jiggle the loose parts around to let the fluid seep into the joint.

    2. This is trickier, but you could try replacing the pin with a spring/roll pin. Basically a hollow pin that applies tension to the opening. It would definitely solve the loose pin issue, but the risk is it might overstress the plastic around it, especially if it's thin.

    Hmm, I'm going to try to put some Pledge into the contact points at the joint. Also, you know if Pledge works for mushroom pegs? Thanks!

    Floor polish should work to tighten most joints. I've used it for pins (Generations Blitzwing) with great success. Will absolutely work for mushroom pegs too.

    For most applications, yes.

    When I was upgrading my CW Optimus Prime with the SND Primo Vitalis kit, there way too much wiggle to fix the waist mushroom peg with future. I ended up using folded paper, in red below, which worked like a charm.

    Thanks. Thats a great idea. Gonna use that for Skullcrunchers hips.

    Also, a very good question OP.
    I've been wondering the thing myself.

    Yeah, it's acrylic you can use a brush and drip it in anywhere.

    I use this method for my loose joints, works like a charm but it's a little scary the first time you do it because if you're not careful the joint will be permanently glued into one position

    This is good to know as my TR Sixshot is an unholy floppy mess. He can only stand if I lean his m against something...

    Pin joints are just the worst, my CW Onslaught has particularly bad ones on his arms.

    Mine was the same way. Managed to tighten most joints on mine with Krazy Glue, but his pinned left knee is still the one joint I've been having issues with

    No need to pop any pins or risk anything using super glue. None.

    An eye dropper, or better yet s syringe, and floor polish. Drop onto joint, work it in, let dry 24 hrs and work agin, let dry another 24hrs and you’ve got a joint that’s tighter than factory. Dead simple and idiot-proof safe.

    The “future” is yours!

    ^This. Patience is key. It may take a couple or few applications to get the job done...but I have yet to encounter a joint Future couldn’t fix.
