Had a guy last summer with a beat up Corolla who swore the $40 single stage from the swap meet was the same stuff we use. Told him the sun would eat it alive but he didn't want to hear it so I sprayed it anyway with a note on the ticket that it was his call. Six weeks later he comes back with chalky pink paint where red used to be and acts like I did it to him. Now I just tell them straight up, cheap materials mean I can't stand behind the work, and if that's a problem they can find someone else.

So you're saying the weep showed up at the bench bleed port specifically, not the lines or calipers? Curious if you bled the master on the car or on the bench, because that port seems to be where the trouble starts for a lot of guys. Did the fittings ever get touched with regular fluid still in them?
