'Morning guys.
Ian, yes that should be a rectangular filler, thanks for noticing it. The kit does have both types included.
Pete & Rick. I have always used regular Halfords grey primer with great results. Models I have painted many decades ago that have had heavy use are still in great shape.
Hi Mike. The hip is coming along very nicely. Just come back from a week in Kernow enjoying some cliff top walks, so can't be bad.
Regards to all Ken
