Ways to fix split in fairing

[kiwi cowboy]

I fill the out side grove with jb weld and the inside I fibreglass.
Well that's on my racebike anyway and it held up well during a 160km off at terrotonga with the fairings holding right together with just scrapping.

Cheers folks. Will go ahead with a 2-part epoxy/glass somefink. Depending on what it looks like mixed, I might throw in some red enamel paint so it won't look so bad if you can see the filler from the outside. Leave it up to the next owner to decide what they want to do.

Put some masking tape on the outside, so that you don't get the epoxy using out too much. You can always throw on a sticker or a vinyl graphic line or some sort to cover it up.

- light sand and clean area
- spread epoxy in thin layer
- put on glass fibre over epoxy
- spread epoxy over fibre... I usually do 2 layers of fibre

I do it all at once... make sure you know the working life of the epoxy, some are pretty short.

Too many damn products... And many seem only for metal.

My first thought was these fiberglass kits I remember from back home which is a tub of pre-mixed glass and resin, then a separate tube of hardener that you added and mixed, then splog the lot over the bit to fix up.

Couldn't see anything similar, unless I wanted to super-size it and get a bucket of resin, so what about those knead-to-activate epoxy puttys? I was thinking it would set too hard for PVC and would come apart if the PVC flexes too much.

Other thought was Araldite epoxy adhesive, but I don't think that would give me a good enough contact area to stop it splitting again. Just because I won't form out for a new fairing doesn't mean I'd be happy with a bodge job. It's got to last a few years.

what is the plastic code on the fairing? are you sure it is-int abs or polycarbonate (pc)
the last ducati i repaired was polycarbonate

ive fixed many fairings in my 8 years as a welder fabricator a weld is far superior than a bodged up fiberglass repair,

its all about the preperation, time and effort put into it
i get called out to sites to plastic weld pipe fittings all the time,
because the glue fails due to poor preperation,

back to the crack,
you need to drill a small hole at the end of the crack this will stop it getting bigger,
its not a fix but it will prevent it getting worse

If you want to be safe with the type of glue, get a two part flexible epoxy. You know you have the right epoxy when you find a 2 part product that is made for plastic bumpers... i.e. car bumpers. You should be able to find it at a hardware type store or automotive parts place.
