i want to know how i can take out the yellow coloring on my fogs...i have the replicas made my depo and the color is starting to turn to a greeish yellow color...what can i use to remove it? in a couple of weeks i'm gonna put on the yellow laminx covers on them so might as well clean them up now...o note that the passenger side has a crack i'm sure its not leaking through because i've washed my car plenty of times and everything seems fine...

 

Paint thinner?
