After I don't know how many years I have fixed my cracked sill using baking powder and super glue, have used it on bike fairings a few times so no idea why I hadn't thought of using it on the sill, really surprised at the result, will be interesting to see how long it lasts, till I kneel on it the next time I guess

I've used the technique a lot.  Lots of vieos on Utoob.  You can use bicarb, powdered metal, cigarette ash, but I've also got a kit with different coloured compounds.  You need a low viscosity superglue for best results.

Interesting about the low viscosity glue, the stuff I used wasn't great but it worked, it ' balled up' rather than soaked into the baking powder, what make did you use?

What's the process?

Put baking powder/bicarb into the crack, drip super glue onto the powder, add more powder if required, it's some sort of chemical reaction between the powder and the glue, I cut the crack open into a 'V' to make space for the powder

Here you go, have to ignore the hole I cut to fix the crack from the inside, have now reinforced the plastic welding with fibre glass on the inside , I'd previously tried to repair the crack with fibreglass resin but it did not hold. The crack was on the outer edge of the sill and about 2 ft long, the bond looks really strong but time will tell of course

Did you drill a small hole at each end of the crack to stop it spreading further?

Good job Ivor. That method of repair is a new one on me; what the Yanks would call 'redneck engineering' on the Insight forum. I would try it on my sill but the damage is too extensive and will require major surgery in the near future.
