One 500 ml bottle of Permanon PSI+14 Silver will make ten (10) 32 ounce spray bottles
with a 5% solution of Permanon. Each 32 ounce spray bottle of mixed
Permanon will coat at least two (2) mid-sized sedans. That's a total
of at least twenty (20) cars per 500 ml bottle of Permanon concentrate which
equates to $5.29 per car/coating...less than the cost of a standard
automated car wash.
