Always skeptical with new products that I have personally never used. There are so many out there they of course all claim to work but we know that isn't always true. Today I used the F9 Barq on a good sized rust spot and it worked just as advertised. No scrubbing no fuss, spray on dwell a little and rinse off. And that was at 50/50 dilution when normally i was using another product at full strength and not always getting the best results. Im sold now!!
