Vortex Generators / Hmmm Airtabs

[JanGeo]

Hey I wanted to test them on my xB which as you know is a big square box with lots of turbulance in the rear - you would not believe the dirt that piles up back there. So what kinds of polish have you been using on the roof? Sounds like maybe you should have heated the painted surface after you cleaned it with alcohol. I think if I were to add them to my roof line I would attach them to the rear hatch in the gap between the roof and the hatch by hooking them on the leading edge of the hatch. Next time used a clean tissue with some Acetone on it to prep the surface. Maybe safety string the back ends together too and then some really sticky clean packing tape over the leading edges. You may have to compound the painted surface to break through the glaze to get them to stick better, mask off the area with tape first and bust the shine on the paint a little - you should be able to polish it back up if it you don't keep them on.
