Debating 18 or 20 gauge. Body guy recommended 20 because it is easier to shape. We are mainly talking about the two front floor patches and two quarter panel patches behind the rear tires. A couple of other small spots. Thank you.
It depends if you’re going to but-Weld or overlap will determine your thickness. Overlapping you can get by with slightly thinner gage on the body...floor pans and such I always go back with equal gage due to their placement.
