I also don't like too much gap as it will want to burn away but I also don't want it completely touching cause one side of the panel will either want to go high or low, and it will be apparent when you grind your welds away. But you can help it out by stretching it back to avoid the metal bunching up. I'm never afraid to ask the questions so that's why I'm asking, metal master.
