Primer is porous, that's why paint bonds to it so well; putting a wrap directly on an unfinished body would probably make it dam near impossible to remove and as has been discussed in this thread, life of a wrap is probably less then a paint job. I've seen a number of cars that have been wrapped (just watch a NASCAR race and just about everyone of them is wrapped; but underneath is a painted body. You would also want paint when it comes time to sell the car; this way if you have something extremely personalized on the wrap, you can make it more sellable if you can take that off.Since the body panels are a composite, is a primer coat even necessary? Seems like panels destined to be wrapped could be left without primer or paint and be just fine. Might even save a little weight but for the size of the Elio that probably wouldn't add up to anything noticeable.
