You can *improve* the appearance of sunspots through several methods, but none will completely restore the original paint:
* Compounding and polishing: This process uses abrasive compounds to level the surface of the paint, removing some of the damaged layer and revealing slightly better paint underneath. This might lessen the visibility of minor sunspots, but it won't be a perfect fix.
* Touch-up paint: You can try matching the original paint color and carefully applying touch-up paint to the sunspots. This is generally a temporary fix and often looks noticeable, especially on larger areas.
* Repainting: This is the most effective but also the most expensive option. It involves sanding down the affected area and applying new layers of primer and paint to achieve a consistent finish. This is usually only worthwhile if you have extensive sun damage.
* Vinyl wrap: Covering the entire roof (or even just the sunspot areas) with a vinyl wrap is a relatively inexpensive way to hide the damage and change the appearance of the roof.
In short, consider the extent of the sunspots and the value of your car. For minor sunspots, compounding and polishing might suffice. For extensive damage, repainting or vinyl wrapping might be the more practical solutions. Touch-up paint is generally not a long-term solution for larger areas.
