Looks to me like they've changed their labels. The one I use on my top is green, but has a picture of a car, boat, and RV on it. It says Fabric Guard. It also has the Sunbrella logo on it - they make the fabrics that fabric boat tops and covers, among other things, are made of.
The Aerospace was blue with the same picture in the middle. The Aerospace used to specify that it is for plastic, rubber, leather, and fiberglass. I use the Aerospace on the toneau cover on my wife's pickup truck since it's naugahyde, or the equivalent.
This is the one I use on the Z top:
303 Aerospace Fabric Guard Water Repellant
That's the first link I found that had the picture of the bottle(s) I have. I'm not specifically suggesting buying from them.
When I run out, I'll look for the Fabric Guard version, which appears to still be green.
Though I've said it several times elsewhere, I'll say it again here - I use a cheap paintbrush (not the disposable sponge type), not that whimpy spray bottle. I put on a couple of coats, then I do it again in a few days. If I don't go through a whole bottle each time, I figure I'm not trying hard enough. I do it at the beginning and end of each warm season.
When it runs I wipe it off the rubber, glass, and paint as soon as I can. It's never been a problem.
