    i have a few cracked ramps on my pins....nothing major but i would like to repair them. What do you guys use other than super glue that works and isnt so obvious (like JB Weld would totally show)....Just wondering. Thanks

    Ive been using a glue called "plastic-surgery" lately. I highly recommend it. Its been doing a great job. Holds fast and strong, levels out nicely and dries clear. I bought it at a ace hardware but im sure you could order it.

    Really good to know...Do you do both sides of the crack or just the top side and let it percolate down through?

    I've used a product called IPS Weld-On before. It creates a chemical reaction that sort of melts pieces together and makes a very strong bond. They make a very thin one that will run into cracks and seal them up

    Jst dont use fiberglass and resin ive seen plenty of ramps repaired this way and the fiberglass has let loose
    i use either acrylic welding adheasive goto the hardwar store and get a good universal plumbing adheasive and primer this will weld the plastics together let dry 1-2 hours then cut a reinforcing piece of abs scuff both sides with 120 grit sandpaper and use the welding adhesive to add a reinforcing plate.

    Super glue can fog up the plastic.

    if they're destroyed I think fiberglass and epoxy works well.

    Ambroid Pro Weld is what you need.
    If there are no missing bits and the cracked piece(s) are still making solid contact, Ambroid glue is designed to actually chemically weld acrylic back together. Other glues remain between the crack while Ambroid sort of "melts" or fuses the plastic back together.
    You simply hold the pieces together and run some glue along the crack (both sides if possible). It is super thin and will get into the crack with capillary action.
    You can use the brush attached to the cap, but a syringe or pipette will allow for a cleaner repair.

    Good luck.

    i use sattelite city hot stuff glue. its a two part high strength glue. put the epoxy glue on one side of the broken piece, and spray a catalyst on the other piece and press the two together and it will bond and harden almost instantly. it can be sanded and polished. dries crystal clear. this is the stuff the granite guys used to fix a chip in my countertop. i bought it at a granite supply store but most hobby shops carry it also.

    There is a testors window glue that is designed to dry clear with no fogging I used on some airplane model canopies.
    I still used superglue on my slingshots and damn the fogging for the extra strength.

    Has anyone tried using Bondic yet? http://notaglue.com
    I bought one, but I've only used it on small things so far.

    #16 8 years ago

    I have used Bondic for a few different repairs. I works, but it doesn't "weld" the plastic. I have found that it will tend to let go with minimal force. The actual glue is strong, but didn't adhere well to the plastic. Better prep of the plastic might result in better adhesion as I didn't prep the repair by sanding to give it better grip. I just applied it to the crack and hardened it. Very likely with a proper prep, it would be more effective.

    Here's a replacement for the ProWeld:


    I think the Flex-i-File stuff is also similar (if not the same):
