Vinylex is great for this, and is very versatile. You can use it on weatherstripping, tires, dashboards, on and on. I always have a bottle in the stash.

Nice. I figured they had something that worked pretty decent to just preserve the top from the rip & tear monster, especially since it's 8 years old. Guess I could make some cardboard cutouts for to 'shield' the windows and paint.
One minor correction: no vinyl treatment is going to stop that from happening.

The "typical" tears in an S2000's top come from the inside out, via friction from the convertible top frame. Vinyl protectants help with regards to UV assault, but won't prevent or even prolong the inevitable.
Anyway. Specific to convertible toptreatments, the best I've used is Duragloss Vinyl and Convertible Top dressing. I was a Raggtopp user for a few years, but the Duragloss stuff is way better. It's a liquid in a bottle kind of like an old Rain-X bottle. You could transfer it to a trigger sprayer, but there's no real need to. Apply it with a sponge. Any sponge will do. Buff off any excess with a "second string" microfiber towel.
Same applies for people having problems with overspray getting all over the car...don't spray stuff directly onto the car unless the directions tell you to.

This goes for anything. Tire dressing, etc., if a product's job isn't to be on paint, or to clean glass, use some kind of applicator.
Examples:
Don't spray directly onto surfaces being treated: tires, dashboards, wood trim
OK to spray directly on: spray-on LSPs like AJT, glass cleaner, "quick detail spray," etc.
You'll save yourself a LOT of window cleaning. And everybody hates window cleaning. Even me.
