Why are some polishes said to work OK in the sun and some are not?



Is this because of the carrier, water vs oil?

IMO, it is always better to avoid polishing in the direct sun. This is especially true on dark colored cars, as the paint gets very hot in the summer months. It may have to do with a polish being petro solvent based or water based. The heat caused by the sun usually causes the solvent, whether water or petro, to evaporate too quickly. This can lead to residue that is very hard to remove. Usually polishes with a lot of oils (Hi-Temp, Optimum, etc.) allow for some usability on a hot surface.
 
I was under the impression, the more oils it has the easier it is to use in the sun. Brad you bring up a good point about the solvent and water based. never thought about that.



Is the SSR line water based then?

Is the polishing out of the sun rule strictly because of the heat? In other words, is polishing in the sun on a cool day a problem also? I'm in northern california, and the afternoons are almost always cool and my car is white. I had planned to do my first polishing of my car very soon with optimum polishes. I don't have a garage at all, so I'm kind of forced to work in the sun, and having some sunshine is actually pretty important for me to see the defects in my white paint.
