The option of taking the kit off when paining was considered but due to the fact it had never been off before and was therefore a perfect fit and had the original black rivots + being unsure whether the fit would be as good again afterwards.

So he decided to paint it with the kit on, the paint didn't really seam to collect on the seam and it didnt crack although it may have done over time?

The paint finish was absolutley perfect with no dust in the paint at all
