Has anyone heard the best way to protect the top? I'm new to this cloth-type top. My Miata had a vinyl roof and deteriorated in Florida because of the sun, heat, and moisture. I had to replace it after a few years, which wasn't cheap, and this new top on the Spider looks like it could have issues if I don't treat and maintain it properly...and may even bleach out over time. Aside from keeping it covered, what is recommended....anyone? Thanks!
