My CF hood is getting yellowish and the color becomes uneven (look at the pic). I wax my CF hood every 2 weeks using optimum car wax. Is it because of over wax? Some people said the uneven yellowish color is due to dirts which trapped inside the wax layer. If I use clay bar to remove the wax layer can I restore the color back to the original? Or do i need to polish? Or maybe reapply clear coat? Please help. Thx
