    Help with customizing ABS plastic dash trim

    In order to put my screen in the dash of my 04 Honda Civic, I've got to relocate my HU to an area just above the cupholders. The plastic bezel piece which runs down the length of the console, is what I wan't to attatch the headunit cage. My problem is, typically I'd use fiberglass but I've heard the most fiberglasses do not bond to plastic. Does anyone have any alternate ideas? The pictures will give you a look at
    A: WHat the piece looks like with the cage mounted in.
    B: What I want the end result to look like, represented by the blue fabric.

    If this plastic is really ABS, you're saved. Everything (paint, glue, polyester resin, epoxy) stick to ABS, as long as you sand it a bit to remove surface agents used during molding.

    2 questions.

    1. It is. But what if it was not ABS, what plastics don't bond.
    2. Do you think fiberglass is the best thing to use.

    Doing my custom dash, the fiberglass stuck to the honda plastic very well. Cleaned it well, but didn't rough it up much. It isn't going anywhere.

    Plastics like PTFE, PP (polypropylen) are hard, or impossible to glue. Some need to be briefly flamed to "reactivate" surface molecules (PP).

    problem is with plastics with a low surface energy, bit of info here: http://www.building.com.hk/bulletin/...2004_043m.html
    best thing to do is try an inconspicuous area before you start cutting.

    Plastic is a pain! I tried a lot of different things on my Saturn dash area. Finally I found SEM Bumper repair which sticks to "problem plastics" Its very similar to Duramix 4040, but you dont need the $80 gun to use it. You can see the build here This was my first crack at this kind of thing.

    Alright! another 04 Civic driver! Just thought I'd give a shout out
    My only suggestion for your problem is that if you live near Troy, NY, I can do some plastic welding for you if you'd like.
    I do have some other questions for you, I'll send a PM with them so they don't clog up this thread.
    EDIT:
    I just realized what you're really asking, and plastic welding won't help you very much with it . I thought you wanted to know how to attach the HU to the trim piece...my bad.
    Old plans out the window because of an accident .
    Have: M1-ATX, EPIA M10000, 256MB, 60GB 2.5", slim slot load DVD
    Need: Time, HU integration, ideas for Lilli

    i heard if you drill a couple holes randomly, fiberglass on the front and a bit on the back, the resin and the fiberglass will seep through the hole, and that is where you will get the penetration and holding strength. just an idea. if it sounds good to you, try it! -Ryan
