Underseal ! , the weight of the paint is part of the cars spec ! 5 KG and no more. When the cars return 2 workshop , they r stripped and sandblasted , measured , re-painted (with the 5 KG of paint !) and re-built. The attention 2 detail is staggering.
Really surprised at how much they gave you guys access to, although were there a few red herrings thrown in.....yeh m8 take a photo of that..he,he,he.....and hope prodrive think some of it is a good idea
