    Glue Experts??

    Anybody know what kind of plastic the OEM airbox is made of? Or what kind of glue (ABS, PVC, ??) will bond this? I know I could use Superglue or JBWeld, but I'd rather have something that will 'penetrate' the plastic better than those. I've already tried a 'combo' ABS/PVC glue, but that peels right off.

    I'm working on an airbox mod, I'll post pics when I get it done....

    Steve, to me the air box looks and feels like polypropylene. I haven't actually tested it but if it is polypro then it's not just resistant to battery acid, fuel and oil it's also pretty much immune to most solvents so it has to be welded, not glued.

      I suspect you're right, but it doesn't hurt to ask....

        I have heard of folks making their own a while back. IIRC, you can take shavings of ABS and dissolve it in acetone to create a "glue" that does have the penetrating effect you are looking for. I have never tried it, but it would be worth a shot.

          I seem to recall some sort of adheasive that will "weld" all types of plastics. I might be remembering something I came across for snowmobile hoods. If I can find it I will post it for you.

            I did finally find an adhesive specifically for the 'poly' plastics (made by 3M) by doing a search, but the minimum cost is about $100....

              Get a tube of windshield sealer from 3M. It's the goop they use when they install new windshields in cars and we've used it to fix dozens of bumper covers among other things.

                  Super glue with baking soda sprinkled on it. Nope, I'm not kidding. Some kind of chemical reaction is initiated.
                  Don't know what type of plastic the air box is.

                    this post couldn't have come at a better time for me. I'm just about ready to take the gold chrome side's off "Spica's" airbox to have them re-dipped. Never thought about having difficulties in reattaching. Sper glue and baking soda. I'll try that.

                      Mack, the trim is attached by pins/pal nuts, so there's no glue needed. Look inside the airbox, you'll see the pins with what look like washers on them. Carefully pry those washers up/off (they're coated with a sealer), then reverse to reinstall.

                      I haven't found anything with the needed structural strength that will actually stick to the plastic used on these, so I'm using pop rivets/aluminum strips to join the two halves.

                      Superglue won't stick either...

                        Have you tried MEK as a penetrating solvent?

                          Or pick up a plastic welder at Harbor Freight for about $60?

                          http://www.harborfreight.com/plastic...ure-96464.html

                          Although I have used superglue and baking soda on many projects with great success. For example, the plastic trim on our fifth wheel trailer cracked ar5ound the mounting screws and was flapping loose. A little superglue and baking soda on the edges of the broken pieces to reattach them and I swear those screw holes are now stronger than the original. Holds just fine even when towing the trailer at 70 mph for long, long trips. Just make sure the parts are exactly where you want them BEFORE you put on the glue. It also is sandable and paintable.
