I've also been using the Meguiar Endurance gel. Be careful as there are two different types. One is a "plain" version (mine came in a black bottle and a High Gloss version (mine came in a clear plastic bottle that shows the purple gel in it. In my opinion, the "plain" version, some refer to is as the matte version, works much better and much less sling than the High Gloss version. If I use the High Gloss version, I make sure that the vehicle that I apply it to doesn't have to go anywhere for at least a few hours and even then, I follow up with a wipe down after letting the product sit on the tire for at least an hour. Both have pretty good durability too.
I also tried Meguiar's Hot Shine tire spray. It has an adjustable nozzle that is supposed to direct the spray in a small to wide pattern. I don't like it and won't buy it again. I just am trying to use up the rest of the can that I bought. I only bought it because I couldn't find the Endurance Gel locally and that's all was available.
I also have been using 303 Protectant on my own car. I prefer the flat matte look as opposed to the high gloss shine on my silver car. The downside of 303 is that it doesn't last very long.
