Not really. I have two strips of road signs material wrap on my service truck. It's so heavy and thick they almost gave up on my request. The road sign vinyl on my truck is easily much heavier than the regular stuff.Oops, I didn't mean to go down the "which is heavier--a pound of feathers or pound of bricks" road. I'm going to take a guess and say a cubic ft of vinyl decal material (100% density) all weighs the same whether it be destined for a road sign or double pinstripes on a 1974 Pinto. If wrap vinyl is 3 mils thick then it should have a wt per sq yard and however much is used could be weighed and compared to paint. I'm sure vinyl wrap people could estimate close enough. Then if the wrap did end up being heavier, how much extra wt would someone accept before crying uncle? If it's lighter, there is no argument!
I know of a couple biplanes with vinyl roundels where you can actually see the texture of the fabric's weave in the surface of the vinyl. Really my biggest complaint is that up close it looks too good. I would just use a company and product that already has a good track record.What concerns me is that a fabric wing has all kinds of lumps and bumps from the rib stitching and how hard would it be to get the vinyl to conform to those? On a Red Bull racer with a smooth carbon wing, sure, but fabric?
