Ok, not much has been done in the past week or so.
I've managed to get the wheels presentable, still not 100% happy but good enough.
I started by stripping the chrome from the wheels and then I repainted them using Tamiya TS-83 Metallic Silver -very expensive but looks good and is a lot more resistant to handling compared to Alclad which I also use.
Then I used the Fujimi supplied tyre transfers, I found it difficult to apply properly at first but eventually I got the hang of it.
I've also carbon decalled the chassis. I made my own templates as the S27 templates don't fit very well and not all the bits for the chassis are present on the sheet. This is disappointing when you take into account the cost of the decals, I would be interested to hear if their later sheets are more complete and fit better.
Now my focus will turn to the front and rear wings, I'm leaving the body to cure a bit longer so in the meantime I'll try to finish the other bits on the car.
