Two Part Question

[TR6speed]

First and I am not sure if this has been asked, but here goes.  I am about to get the car ready for the first major show of the season and I need to polish the car to remove the original UV Spray Ceramic coating.  My question is how do you maintain the spray coating once you open the bottle and use it?  I was checking my supplies and noticed that even though I cleaned the sprayer and pickup tube after it was used last, it feels sticky, and nothing is being picked up.  I took the sprayer off the bottle when I finished the last application pumped it until no further product came out.  I then used clean water and sprayed it through the sprayer.  If this means the product has crystalized, I assume it is no long any good.  Is that correct or is there anything I can do?

Part Two: I need some supplies and if the UV Spray Coating is no good any longer, is the recommendation to step up to the Graphene and if I do Can I still use the CS3?

Hey Jack,

I would say the Spray coating would still be good, I would put a new sprayer in before using.

Hope this helps.
