I don't know about the rustproof/undercoating, but I do know that the paint protection (if it's something like polyglycoat) isn't any better than a good wax job. Even if you do opt for the paint protection, don't beleive that you don't need to wax. You should wax at least 4 times a year with something like "Rain Dance", and use the paste, not the liquid. I had a Polyglycoated Scirocco, and the paint faded within 2 years (under the Texas sun). I foolishly believed the "no wax" hype. E. Muroga
