I've been tempted to try their products, but the problem is - well, money! I swear I've had the worst run of stuff breaking and the list of home improvements the wife and I talk about is not just cause we want a "new look". I have tried a lot of stuff, bought a lot when I started and then realized I could trade and barter with others and try a little without buying a quart. I must say that I'm pretty satisfied with M101/105, D300 and BFWD and they can do anything I need to do for any car that rolls in my garage. I've still got a cabinent full of waxes, glazes and special stuff like KIAO that I keep. So, from what I'm hearing, Surf City is good but not way above enough for me to replace what I have, I do miss trying new stuff though!
