  • What do i use to bond PP plastic and Xenarc case?

    I have tried bumper repair and epoxy. I have tried fiberglass. None of it will stick to the plastic of my Honda Element.

    So i sand down the shine of the plastic surfaces. Then what do i use to mount them together? What can i use as a filler?

    I get the idea of how this is done, just need to find stuff that is workable and will bind with Poly propelene plastic
    Take my advice: Do not try to build a system that includes EVERY feature. Start with the basics, build it to a bug free state, and THEN add on.

      Read up on that. Will it work? I'd hate to mess up the surface trying.

        This post says acetone will melt both PP and ABS. Check out post #100. Then someone suggests using PP and ABS chips together to bind it to ABS.

            Prepare the surface of the PP with 3M 5907 adhesion promoter per the instructions and then use 3M Automix Plastic Adhesive/Filler.

                  Another Element owner! I'm in the process of putting together a carputer for my Element also.

                  I just recently fabricated a Xenarc case into an Element bezel, using Oatey's ABS Cement. I chose the ABS Cement because it was already pre-mixed and came ready to use. Cut the bezel to fit, sanded everything down, then applied the cement to glue it together and let it dry. I had to do several coats because I kept getting little valleys where the cement was. Applied probably 5 coats of plastic primer, sanding in between each to smooth out the bumps, and now I'm about ready to paint. I've given the new bezel a little bit of a twist, and it seems quite solid.

                  Any tips on the painting process? Where can I find the SEM paint that everyone's talking about?

                            you could try this stuff, which I think they carry at home depot.



                            it is basically epoxy with some plastic solvent in it, so it dissolves the plastic a bit so the epoxy can solidly bond to it.
                            But don't take it from me! here's a quote from a real, live newbie:
