If you don`t need to weld stuff up and can put a grommet instead, then that`s what I`d do for two main reasons. If you weld it up and need it later on in the day for a little something else then you have made extra work

And the more welding you do, the more chance you got of rust coming in places where you never had it before, so try and keep the welding to a minimum especially if you ain`t sure when it`ll get painted or if you can get to both sides to paint etc etc :mrgreen:
