Hello everyone, I was looking for a local detailer to decontaminate and detail my SUV during the winter while my hose is packed away. I found an authorized installer in South Bend and when I reached out he said he wanted to use a clay bar in addition to IronX. The website seemed clear that you should not claybar the ceramic seal. He said he would be careful but I am not sure why he is pushing for that. The color of the vehicle is black with blue sapphire specs. Thanks for your help.
