I read all above year 2016 subject on a clay preparation, waxing brands, and shine brands. Should I do any one or more on my 2004 X - Type, forest green sedan?: My roof and trunk surface have large Florida rain & heat corrosion spots (paint is fading). I will get a full paint job 8 - 12 months from now, but don't want my surface to get any worst. Anthony
