Thanks for or the info. I'm sure I'll have to get to the stage after maybe watching some videos with some claying guidance. Depends how bad the car gets. I'm tempted to just take it to my detailers once a year and pay the small amount for a quick decontam after every winter say.
Yea that would be more than enough. I like a guy on YouTube called Larry from AMMO NYC. He always gets asked how often a car needs claying and he answers "how often do you go to A&E?". It only needs doing when it needs it!
Good test is to get a paper bag and run your hand along the paint with your hand in the bag. If you can feel any sort of rough texture, then its time for a clay.
