Is this just a small bottle/applicator of 303 Aerospace Protectant?

I'm willing to bet it's just AT-205 Re-seal, watered down. Back when I used to watch Scotty Kilmer (before he got super whiney & political), he showed that AT-205 & water will "recondition rubber" like it does when used in a trans/engine/power steering system/diff. I use Dielectric Grease (pure silicone grease) to keep the rubber on my car nice & supple. I apply it with my hand, let it sit & soak in for a few minutes, massage it in a little, then wipe it down. It works beautifully, and keeps the rubber (tires are treated differently) looking/feeling/performing as good as or better than new.

Can this be used on sunroof seals?

I do not see why it can not be used on sunroof seals. I just purchased the rubber seal protectant but I have used other 303 products and love them.

Is this product better or worse than einzette gummi pflege? thanks!

Hello,Einzette gp is generally used for interior rubber, as it is water-based and will get runny when wet. It is still very effective on exterior rubber-like components if buffed dry tokeep excess liquid at a minimum. Einzette can be used if you are willing to work just a bit to buff out your exterior rubber to a nicw shine; it is not a spray-and-forget type ofrubber protectant.I sure hope this helps.

Can the applicator be refilled once all 303 protectant is used? Or is this a sealed cap that once it's empty you have to buy a new one at $9.98.
