    What type of plastic is the fairing on my K1200LT made of?

    I'm getting very close to being ready to reassemble my K1200LT. I have bought all of the parts to make it rideable, and only lack a few cosmetic pieces to make it gorgeous again.

    My right main fairing has a couple of cracks at the bottom. If a don't fix these cracks, a small section of plastic may someday fall out. The cracks can be fixed by putting a patch on the backside. The repair will be nearly invisible, unless I point at it. I have a nice double barreled epoxy gun with a tip designed to mix the two parts together as I squeeze the trigger. My question is, what kind of plastic is the fairing made of so my supplier will know exactly which product to sell me? He and I are thinking it's ABS.

    Does anyone have any suggestions as to what type of adhesive I should use? I know the body shop supplier will, but his are not the cheapest, and may not be the best.

    Thanks in advance for sharing the vast knowledge of this group with me.

    There should or may be a marking on the back that will say.
    I know there is on the 800ST. However, I found that any good epoxy for plastic would work.

    A lot of the epoxys don't soften the plastic for best adhesion. I think those that soften the substrate do the best job.

    If you're not living on the edge, you're probably taking up too much space.

    Well, therein lies an interesting question.

    How does one say ABS in German?

    On the backside of each main fairing, adjacent to the part numbers, I see >PBT+PC<

    On the backside of each lower fairing, which seems to be a slightly different, more pliable, plastic, I see >PA6+GF10+ MIN20<

    Are these the identifiers for the plastic? If so, what do they mean?

    I don't see a USA variety of recycle symbol.

    Here's some helpful info:

    It looks like the PBT+PC can be melted (welded). Check with a local body shop or supplier for products to repair. Also note that it is chemical resistant.

    From what I could find on the PA6, it is a 10%glass filled (GF10) Nylon. In my experience this would be difficult to repair.

    They are ABS plastic. You can get two part epoxy for ABS at most auto part stores.

    Lower cowl broke but good.

    The lower cowl on my 87 K75S was cracked and wobbly from about the sight glass hole to the rear mount. I was a bit concerned it would just break off or worse, vibrate and make me crazier than I am.

    I gouged out the crack with a knife, filled with Evercoat's Maxim urethane plastic repair system, sanded, painted and it looks like new.

    It's expensive and time consuming but I'm thinking I could attach a hook to my lower cowl now and pull Semi's out of the Rhubarb.
