Our coating permanently-bonds to the paint and sustains its top performance for at least 3-4 years. It can only be removed from the paint by mechanical means, such as sanding or heavy-compounding. One of the main reasons for performance loss is scratching. If a ceramic-coated paint is not washed correctly and gets highly swirled and scratched, the loss of superhydrophobic properties becomes noticeable sooner. To sustain the top performance, we recommend you get your car washed using always "gentle" methods. This doesn't mean you cannot go to a drive-thru car wash, as not all of the drive-thru car wash places are the same. With proper care, you can benefit from the great properties of our ceramic coating for long years.
