Currently Rimguard is around $1.75/gallon at my location. No idea what service/installation charges are. However, I check tire pressure with a "dry" gauge without any problems. Bring the valve stem to top dead center, blow air INTO tire to clear any fluids, check tire pressure. I've used this method for over thirty years - including many years with CaCl - without any problems with any gauges.
