Weather, paint and LSP

[Capa1970]

What is tougher on paint and LSP, consistent sunny warm weather like Florida and S. California or weather that bounces all over the place like Oklahoma? We recently had the hottest month on record in the US and we own 2 of the 3 hottest three month periods on record also (Texas the other). We freeze very often here for many days as well. I assume the weather changes expands the metal, paint and clearcoat. I am also assuming that that isn't very healthy?

I am in PA. I believe that CA weather is the best for a paint's finish (if cared for) due to the fact that it does not fluctuate so greatly. But the baking sun might hurt interiors. Of course that depends on where in CA. FLA weather I think can be hard on paint with the humidity and frequent rain (usually salty). Our PA weather is a beast on a car's finish. Road salt, acid rain, humidity, baking sun, snow, ice, and road anti-skid. In PA you can not wash your car year round outside to remove the corrosive elements. I think your OK state weather is not ideal either for the reasons you stated.

Thanks for the reply. I'd rather leave salt out of the equation since I know that turns the tables. Anyone else?

I believe you're talking about the effects of temperature and not weather, snow, ice, sand, and salt or exposure to daily temperature extremes.

I've never seen or heard of paint failing due to cold but the relentless assault of the sun has done in many a paint job...

Heat or cold my money would be heat doing the most long term damage.

Thanks Bobby. So, ignoring the salt and sand, you are saying that constant sun and heat is tougher on paint and LSP than heat, cold, heat, and cold. I am asking because I see a lot more cars here with clearcoat failure and oxidation than I remember seeing in California (where I lived for 20 years). I wasn't sure if this was caused by the extreme weather or by the car manufacturers cheapening the paint.
