I’m wondering is someone over here knows if there are sealants that can be put over nuba? So far I read that OS can be applied over nuba and was wondering if there are any other ones that can do that. I would like to protect my car before winter but I really like how PS looks on my car and I want to add some more protection with out stripping it. Note that I don’t have a garage so I’m not always able to clean my car during the “cold� months:wall. Thanks for help.
