I've been trying to avoid that process though. There are so many electrical connections and I know that many of them are hidden from sight. I'm afraid of getting them wet and creating a bunch of problems. I had a friend who did that and he ended up rewiring a portion of his car. I know the process I'm using will take a long time but it seems to be the safest and most thorough. I wish someone made a kit with specialty detailing brushes though...
