The scuttle is the same size as the one on my car gave or take a couple of millimetres,
The body work on my car came from Martin Keen. I have tried not to make it look the same.
Do you have a spray booth at your work shop to but finish on the bucks? The high build primer that I have used covers all like a tight skin. I am very pleased with the finish and will give then two coats of lacquer be for polishing.
Could you post some pics of the single seater in progress.
