The Great White Brick - '69 Valiant

Neil, I've got to ask.....what in heck is Master Series - other than golf I guess. :) You're in Ont. so I'm assuming it's a product available in Canada. Also, you've intrigued me with the use of WD-40 for cleaning the barnacles off 'er bottom. Could you explain at what point you use it and what it does for you? This enquiring mind sure wants to know, because I'm scraping the barnacles off the bottom of my Vart right now.
Thanks.
