I bought a small bottle of this to stop my lights yellowing.
I polished my lights today so went to try this product for the first time. Although I bought it a while ago, the expiry date of mine is 12/29 so I opened the bottle and nothing came out. I took the label off to see what was going on to find this;

It is completely solidified. Looking on the net I checked the amazon reviews and what do you know, all the 1* reviews I started reading (15% of the reviews...) had either the same thing or not drying, or yellowing after 2 weeks.
If you must try this, use it straightaway and buy from someone who will do a refund!
(Just to add perspective, everything I have ever tried has failed though).
Shocking. I wouldn't use that product at all, even if it was free.
I used it on mine after polishing up the lights, no problem 2 years later
