Tried a new weld prep paste last week and it cost me half a day

I saw this stuff online that said it would cut my cleaning time before a pressure weld by 75%, so I spent $45 on a can. It left a weird residue that actually made my first two welds fail the dye test, so I had to grind them out and start over. Has anyone else had a bad run with a 'time saver' product that just made more work?

My shop bought a batch of those quick-set epoxy patches last year. They never fully cured, which led to a slow leak in a coolant line. We ended up having to strip and redo the whole run, a real mess.

Did you ever get a refund from the supplier?
