That is time consuming, to put it mildly, but critically important! Glad you have the patience!!!
Yeah, it wouldn't be nearly as time-consuming if I didn't have the habit of looking at it and thinking "this is going to be critical to life and have to last at least thirty, possibly forty years." Then ripping out the "okay" and redoing it to "darned good."As it is, wow, this is going to take some time. Not as bad as getting every last speck of corrosion off the ribs, but quite some time.
