I started drilling out the spot welds on the drivers trunk floor today. There are quite a few 'hard to reach' welds, especially along the taillight panel. My drill is too big to drill straight down. How do you guys do this? Do you just drill at an angle and try not to take out too much of the metal below, or do you do something else? From what I can tell, this is just the beginning, there are going to be lots of tough ones.
