Have decided to delay the Powder coating for a week.
I changed my mind a couple of times about the two small 1ft upright tubes on the outer rails that sit just in front of each door. These two rails whilst both being solid metal are showing some early signs of discolouring and are concerned that even with shotblasting, rust could eventually creep through. I have therefore decided to replace these hopefully over the weekend and get the chassis in early next week.
For a few extra hours grinding away in the garage I will have piece of mind that underneath the fresh paint to be applied it will be all fresh metal in all the usual problem places,
