There is a commercial for a spray on paint protector called “shine armor”. In theory, this looks good! I have a Honda Accord 2017. Alas, when washing my car, I caused 2 light scratches on the hood. Somehow, the microfiber towel was no longer as soft as the first time I used it. Supposedly you can drop a bucket of screws on the paint and it won’t scratch. Should I have any and all detailing done before using it?
