Big green headache

Do yourself a favor and ditch the vinyl top and just have it painted that color you wanted the top to be i.e. Black, brown, white (did they even offer a white vinyl top?). This way you'll never have to worry about rust under the top. Plus if you want to give the illusion that there is a vinyl top, just put the trim pieces back on and at a quick glance (or until they get close) it will appear as though there is on the car. Sorry to get off topic on your thread, went out to look at my parts car (which has a vinyl top and it's nothing but rust there).
