Dark paint looks its worst in direct sunlight. Fine swirl marks and hairlines from a sponge, towel or car wash show up in it. None of them is visible on its own, but together they scatter light and black stops looking black, even on a freshly washed car. You wash the car yourself or have it washed often, and you don't want to have it polished every few years.
That's what FEYNLAB Heal Lite, a self-healing ceramic protection, is for. Fine swirl marks that form in it during washing level out once the sun warms the layer. The paint doesn't need polishing to get rid of them. The manufacturer states a lifespan of up to five years and recommends the self-healing protection mainly for dark paint.
