Got a chance to use F9 BARC on a residential cleaning for irrigation rust removal here in South Tampa, FL. Over all, it's DEF a great product.. a bit pricey tho but I'll still purchase move in the future!
@ Doug.. yes, I diluted 3:1 mix. I followed your step about rinsing first, then appling the F9 and then rinse again for painted surface with repeated if necessary.
