You do you use on your vert top? I bought the 303 kit for fabric tops a couple weeks ago, and it seemed to work pretty well. After the protectant dried, water would bead up like mercury on the top. However, after a heavy rain (a week or 2 later), it wasn't beaded up like I expected.

What do you use on your top, and how does it work? Also, how often do you need to re-apply?

i use mine a bit. my friend used something on his cloth miata that he said did a great job. i'll find out what it was. i've had my car just a few weeks, and haven't moved up to cleaning the fabric top w/ specific materials.

Raggtopp, 303 or Porsche Tequipment. After a heavy rain with any fabric top, the protectant will wash off (nature of the beast). Just reapply. You're looking at treating it monthly in good weather anyway. Shampoo it as necessary.
