  • plastic reinforcements (kickpanels/speaker baffles)

    So i have those flimsy q-logic kick panel enclosures, some plastic deals that screw into my doors and make a mount for a speaker, and some plastic adapters to go from a 6x9" speaker hole to a 6.5" & tweet component...

    With the quality items i'll be installing in these enclosures/etc, i'd rather they not be so flimsy/flexy.

    I've used bondo only a couple of times, and have yet to start a fiberglass project. What i'm asking is what is the easiest way to reinforce the backside of the kickpanel enclosures and door enclosures, and the whole of the plastic plates that are my 6x9 speaker adapters?

    At first i thought just to paint some fiberglass resin on the items and place some of that mat down... But after searchin the forums i get the impression that this will not stick to plastic all too well.

    As for bondo, it sounds silly to slop a bunch of that over a large area just to make it harder... Sounds like bondo is more for shaping and filling, not at all for this.

    I don't know if such a substance exists, but it would be nice to sort of dip these items into something that makes them super hard But that sounds far too easy.

    Any thoughts?

      ehh never used "foam"

      infact when i hear the word a variety of materials comes to mind... can you describe it? that sounds like a tough fabrication material to google...

        Two-part polyurethane foam. Look at this: http://www.shopmaninc.com/foam.html

        I don't think that would be an easy solution though.

        I would probably heat some thin ABS sheets to shape and glue them in. Or, since I'm currently working with liquid plastic for several projects (see the solvent adhesive thread), whip up a thick version of it and spackle it in. That might even be the easiest solution, and you would be left with one solid unit, as rigid as you want it to be.

          That $4.95 epoxy "abs repair kit" stuff is badass too man, wont work with PP, but becomes one with abs type stuff, its in a solid black 2 joined tube package, its at most hardware shops, I use it for mounting/joining anything abs now. The mixture if abs into acetate works too BTW

            I'd just take can of fiberglass reinforced bondo and coat the inside with it... Let it dry, problem solved.

                eh i wanted the premade ones because they matched the color/texture/trim design of my current interior

                i suppose i can try the bondo, but if i decide to lay some fiberglass material in there instead, is there anything that will help the resin stick the material to the plastic? the inside of these kicks is very smooth, is that better? or should i sand it real coarse?
