If the color doesn't matter, I've had good luck using 3M Rigid parts repair and SEM problem plastics repair on the plastic cladding on my Syclone, the 3M is blue and the SEM is tan. The 3M is available in 5oz tubes that you mix like JB weld, I believe the SEM only comes in cartridges. I had to make several repairs so I went with the 200ml cartridges. I did have to buy an applicator gun, but I was actually able glue a piece that had broken in half back together using a mesh backing for support. For the smaller cracks and holes i just used painters tape to give it a basic shape.
