Just got to tackle these tricky little sill end finishers.
The one thing you have to keep reminding yourself is that this area is so prone to rusting due to water get into the sill. So I needed to make these sill ends as watertight a possible, but also ensure that they fit smoothly, so not to remove the primer. Not easy and takes a lot of small adjustments before welding it all in the set position and drilling the welding holes and spraying on the weld-through primer.
I have been preparing the other three areas as well all in the same fashion.
