Well i tried vortex tape on ahead of the rear edge radii on the tailgate of the last polo, and now I want to try peeling the laminar flow off beyond the existing the panel length (kammback theory) with a flexible edge (the tape) thus giving a more gradual separation. gonna try the theory on my wing mirror first where I can keep an eye on it

p.s. you noticed clio wing mirrors are terrible in the wet? mine were, spray kept flicking round the edge and up on the mirror face! result HUGE lack of reward vision!
