The order of the brazing rods came pretty quick with in a week of purchasing them online and usually take couple of weeks living here in alaska. I purchased after looking online from one of the posts and wanted to try them out. Living here in alaska we use the riveted aluminum lund boats all summer long and on 3 rivets that had a little crack on the boat sure helped a lot! No more leaks and will be purchasing more in the future when i need them!
