jody pm'd me yesterday and informed me that dirt found its way under the magnetic bra on her vx and that the dirt had rubbed on the painti just went out and took my bra off to see how it looked underneath (LOL) you could see the pattern of the magnet on the hood very faintly from certain angles, just using some spray on detailer and a soft cloth it came right off...
moral of the story, when you install the bra, make sure its warm enough out that you get a near perfect fit, dont want any air bubbles, make sure you clean the you know what out of your hood and bra before putting it on and its not very difficult to take off and reinstall, so for some extra insurance make sure to take the bra off every so often and wash underneath it, bob recommends every month, i will probably clean under mine every 2-3 weeks because i park under a tree that drops all kinds of crap on my vx
yes the bra is easy to take off and put back on (although i have no idea why someone would put a bra on after taking it off) once the bra has been installed once, it kind of forms to the hood, so its very easy to get it lined up again
