Chrome or anything metallic will get hot in the sun. White is the best color to keep things cool. Why, because of the spectral emissivity. Silver and chrome reflect and emit the same at visible light and infared light (heat). White paint with titanium oxide reflects light and has a high emittance in infrared, therefore needs a lower temperature to radiate the same power as silver or chrome. Just try it, put something chrome and something white in the sun. Ive had chrome wrenches in the sun that were too hot to pick up. The roof of my RV is painted white and is cool in the sun. The whole premise of putting chrome wrap on to keep cool in the sun is false, unless your car is black.
