The paint would not stick and it pulled away leaving little holes to the primer all over the place! As I recall I re-sanded the panel and wiped down three times with PPG DX330 using two rags, one wet and the other dry for the final clean. Change the rags often. I buy a bag of 250 lint free rags from Home Depot @ $12.00.
They make wax free tac rags. Last car I painted I just cleaned it good with final prep, did not use a tac rag and the paint came out perfect. I think it has more to do with the environment than the tac process. If theres dust/dirt in the air will fall after you tac anyway! I do the same with the rags though. I will wipe down turning the rag over a few times initially. Then I will fold the rag, clean one swipe, turn the rag. I keep at this until after wiping the rag comes up clean. At that point the metal should be ready for paint.
