Im gonna go with straight simple green, not diluted or anything. It has a real manly smell you know like if you get it in your mouth you might die kinda thing....
But when im feeling not so manly I like the smell of XMT glaze, reminds me of grape airheads.
Tough call there. I think it would be a three way tie between Meg's Quick Detailer (not sure what it is, but I like it), Danase Turbo Shine (tropical fruit Life Savers) and Nattys Blue (bubble gum).
