I can see why Rick is so passionate about plastifix.It is great stuff.I just fixed the front fender of my black FJ.I didn't have much time before the bike had to be back together for the WCR so they aren't perfect but it will be easy to go back later and put one more coat on and use fine sandpaper to finish it instead of a big flat metal file. plastifix puts into your hands the power to re-create all the fairing parts.I'm going to try and make a complete fuse cover next.

I use plastex. It comes with a reusable mold making rubber bar just heat it up in hot water. Great stuff. Plastic powder. With a chemical that melts it into the plastic of the chin spoiler. Just use fiber glass cloth to reinforce It on the back side.put plastic powder on both sides of the fiberglass cloth and it's inside the plastic.if you do it right you will hardly see the crack. the front. You can even fill in missing pieces
Ordered some Plastex with fibreglass mat, Thanks

Be sure to cut the groove on the backside of the plastic to make room for the powder. Like the video only you don't have to do it on the front. So you can get away without paint work.

I just  use ABS plumbing cement, which is nothing but the same plastic and a couple of solvents.

Fairings are literally made of the same stuff as drainpipes.

For a crack like this, I would definitely reinforce with fiberglass.

Plastex is awesome for fairing tabs etc, you will have good results Krusty. And as Giantkiller mentions, use a dremel and cut a V when joining 2 pieces of fairing for example. One thing Plastex says to do is have the liquid in the dropper, and pick up some powder, reapply etc. Too laborious, now I just pour some powder into the crack or V, and drop the liquid on top, soaks through the powder and sets beautifully,

When I got back from the WCR I took the front fender off of my black bike and made molds to repair the missing lower tabs on the front fender of my yellow bike.Once again it worked well.I also tried my black fender on my yellow bike.I think it looks better black.

Plastex works quite well, I have noticed one more crack which I'll look at repairing but it's underneath the heat shielding.
So when I take off the shielding it's gonna fall apart and not be reusable, so what can I use as a replacement?
I've seen thin fibreglass mat with foil and sticky, Will this be enough?

I just watched the videos on both the Plastex and the Plastifix websites. Essentially identical from what I saw.
What is a practical yield from the volume of material in a basic starter kit, which Plastifix lists as being 30g of powder.

For example, how many missing tabs for the air scoops or on the rear panels could be totally replaced with the 30g?
If someone wants to see any images I refer to in posts, first check my gallery here. If no bueno, send me a PM. More than glad to share.

I bought the proffesional size kit of plastifix.it comes with 150 grams,75 grams of white powder and 75 grams of black powder and a large bottle of plasticizer,three molding blocks for $132.00.Ive created several tabs and repaired several and I haven't made a dent in the bottles.It would make dozens of tabs.even thirty grams should make several.

Some repairs on my daughters 250 ninja.
They were done with abs plumbing pipe disolved in MEK to make a paste then v grooved the back and layer in.
After it set I v grooved the front and filled. When it hardend up I smoothed it out.
It is not perfect but she will paint something over the repair.
