i currently use kit carnuba car wash and wanted to know should i do anything before i switch and what soap should i use

 

Switch to what?
Usually a good washing with Dawn dishwashing liquid will prep it for a different polish.

 

different soaps i just want to switch to somthing else

 

I use Meguiar's Car wash and it is the soapiest, suds-iest carwash I have ever used. Works great!

 

gold class? if so i wanted to use that but should i wash with warm water or anything before i switch. we have had killer storms and its finally nice and i got time to wash her now havent washed it in a week but rain water has hit it and mist from sitting under my car port

 

Yup it's Meguiar's Gold Class. I really don't think you have to go thru a process when only switching car wash soap. If you want to remove the wax that is currently on your car, many recommend using Dawn dishwashing soap (minimal amount; cuts the grease). One you use the Dawn, I would give it a really thorough rinse and then go through your polish/wax process to get a protective coating on that paint.

 

Duragloss CWC has the most lubricity of any car wash I've used.

I like the Meguiar's Gold Class. Read good things about the Duragloss shampoo as well. Can't really go wrong with either of them.
