How does this magic product know which small holes to seal and which to leave open? Why would it leave open an orifice over a leak in the system? Must be smart chemicals. I am betting the subsequent clogged system repairs follwing this product's use are common.

Good luck, and remember with this and anything else, if it sounds too good to be true, it usually is.
