my brother doesn't use forums and doesn't even know what rinsing is, he runs his system at full pelt and washes away, I know he does a good job as we do some large commercials together outsides then in, I on the other hand use forums and started rinsing off, then rinsing on then using flow controllers and eventually got rid of the controller and just rinse on but in reality I don't really do anything differently from my brother
he used to sub a job out that is due this sunday, the company he subbed to used two men that took 7/8 hours to do the external glass, they had flow controllers rinsed everything and took ages
we will do the same area in 90 minutes on sunday morning, and then we will do internal and I have never seen a bad window but there was often problems when the other company did it
