Anyone using Blendco chemicals in their tunnel?

The Blendco rep for my area has been stopping by lately trying to get me to try out the new Tunnel Vision line of tunnel chemicals. This is the powder based chemicals. I like the idea of having the raw active ingredients for the chemicals right there instead of the pre-made chemicals. Plus why pay for shipping of 55 gal drums when it is 90% water anyway.

Rep says he can reduce my chemical bill by close to 50% compared to my current chemcial line (Blue Coral).

Anybody have any opinions on this line?

Be careful of what a rep tells you. Too many of them will say whatever it takes to get you to switch, but they can't have a clue what it will really save without actually trying and dialing it in properly.

I am not to keen on blendco. I have only seen 2 tunnels use it. One owner doesnt know any better, and I think that the other tunnel seems to be happy with it (but they havent tried anything else) I have switched many self serves off of it, but never a tunnel (I am 0 for 2 if you can't tell) What is your Blue Coral CPC? cut that in half, does that seem like a realistic CPC for a clean dry car?
