Aright so when I bought my truck the heat extractors on the hood looked amazing but when I washed it a few times it faded to that ugly nasty gray/ calcium build up that water leaves behind. Did a bit of research and have descided to narrow my list with with one of the two, Adams and the Chemcial guys trim restor kits. Anyone wanna help or put in their two cents on which one works best and last the longest? Appreciate the help
