A guy in Knoxville told me my seams were showing because I was rushing the iron
I was doing a 1200 sq ft job in a rental over on Chapman Highway and the property manager walked through and pointed at every seam. He told me straight up, "You're moving that iron too fast, the tape never had a chance to melt." So now I hold it down and count to 6 before I move on to the next spot. Anyone else got a number they count to, or do you just go by feel on the tape?
