Can anyone tell me any tricks or concerns I may have or need to know when encounting rivets on the side of a trailer. I'm going to do some basic lettering and graphic applications to a trailer and I will have to deal with a bunch of rivets. I'm just using vinyl and I'm guessing I can basically just apply the vinyl over the rivets then go back and rotate my squeeze around each rivet head to make it more contour. Is that right or do I need to watch out for anything any and all advice is welcome. Thanks
