A car cover protects an MX5 NBFL (2001–2005) from dust, dirt, and other external elements while it is parked. A clean body also reduces the risk of dirt under the cover scratching the paint. It is therefore advisable to thoroughly clean the car beforehand using polishing and cleaning products designed for the MX5. This not only protects the paint, but also ensures the cover can be placed over the body cleanly.
