You are absolutely right, Kevin and we will look at this very careful in the next days.
I will attache a picture looking at the mating of the angle strip with he wall and it is interesting that we have no 'swelling' between both, angle strip & wall. This is incredible for a 77 year old truck that has spent most of his life outside. The reason is probably the lack of moisture in our country and the only 250 mm (10") of precipitation we get in a year.
Taking all the spot-welds off is very time consuming and attaching it with screws changes the looks, too.
But, we will need to make a decision soon, before the thick walled pieces go to the sandblaster. Cab, fenders, etc. I will probably chemically paint strip and hand-sand.
