Our coating permanently bonds to the paint and sustains its top performance for at least 4-5 years. It can only be removed from the paint by mechanical means, such as wet-sanding or heavy-compounding. One of the main reasons for performance loss is scratching. If you do not wash your ceramic-coated car correctly, swirls and scratches will develop on your car's paintwork and will expose the uncoated bulk clear coat, which – eventually – will reduce the superhydrophobic properties. To sustain the top performance of the coating, we always recommend a gentle wash. This doesn't mean you cannot go to a drive-thru car wash, as not all drive-thru car wash places are the same. With proper care, you can benefit from the beautiful properties of our ceramic coating for long years.
