I've read that the 303 Protectant is an excellent protector/sealer for convertible tops, better then RaggTopp.

Mike I've been using Meguiar's products for a long time. I like their Gold line, and really like their Quik Detailer Mist & Wipe Spray (this stuff rocks).

I've yet to try it, but I hear great things about Meguiar's NXT line, many say it's on par with the Zaino line.

I also really like the Zymol product line, their leather conditioner and wax is terrific.
