Long term appearance of lighter colored tops- Opinions?

[Quickurt]

Thanks for the info on Ragg Topp. I'll take the seconded endorsements here to heart.
They also have a product I hadn't considered, the convertable leather interior cleaner and protector. I've had several rag tops over the years, but the boxster is my first with hide interior. Makes too much sense that the leather is going to take way more of a beating in the convertible than in a coupe.
Just ordered their fabric top kit and leather kit.
I also got Aerospace 303 vinyl cleaner/protector for the seals. It arrived today from Campmor. They were the only supplier that came up on google who had it in 8 oz bottles (and the best price on all sizes). I hate to buy a big bottle of something to try it. Like everyone else, I'm sure, I have a couple of shelves with stuff I bought and used once. From reading their supplied information kit, I'm going to use the 303 on my dash. Maybe the sand beige shows it more, but the dash seems to really pick up crud from top down driving.
