    Polyurethane adhesive?

    So im trying to fill my bumper holes, fill in all the scratches, and extend a lip. Is there any adhesive that i can use to fill, bond and able to sand down that is compatible with Polyurethane and wont crack under pressure like fiber glass?

    Best Regards,

    That's not even the correct screen cap from the movie. Whoever made that fails.

    If you’re trying to fill in bumpers you have an option of three different things depending on what your bumper in made of.
    -Plastic bumper use the plastic bondo.
    -Fiber glass bumper/cover use fiber glass bondo
    -Hard bondo is only used for metal applications. If used on anything else it will most likely crack.

    With PU, bondo would most likely to crack since the material is flexible and is at the front of the car closest to the ground which means it will vibrate or under wind pressure.

    hmmm, i was thinking a silicone rubber and plastic compound. Somewhat like calk (white stuff you seal water in the bathroom corners/edges) But it may be to weak.

    Oh and dont use caulk it will just come loose and fall off. If you can get a good scratched up area to work the bondo onto you should have no problems.

    I used silicone rubber compound to do something like this and it worked good for me.
