I have had my CanCoat in the original bottle for about 14 months, it’s still looks fine, and works fine. However, the top was getting a little crusty and rough to open, so I transferred it to an a hermetically sealed mason type glass jar. The original bottle is pretty cheap, imo, with bad sealing capability. The idea that they give you three sprayers, just illustrates how half baked Their idea is for longevity. After I crust over the sprayers, what then? This stuff is too expensive to waste with crystallization.
To use it, I take a microfiber brick with a medicine dropper, put 3 to 4 drops down the middle, and then apply it to the surface. I can see it go on, and with a quick buff the surface is perfect. It works every time. I use it all over my painted parts of my motorcycles, and my helmets every 6 mo or so. I no longer own a car but the application of CC I put on 9 mo ago looked good when I turned my lease in.
My medicine dropper cleans out every time with isopropyl alcohol. So I have no idea why they can’t recommend you cleaning out the sprayer the same way instead of giving you the three that are going to eventually clog up and become trash. I may be missing something here, but…
