My 67 Formula S Resto. thread

I took a break and worked on the car only a few hours yesterday and a few hours today.I got the rear valance and the outer wheel housing welded on.I went ahead and removed the upper cowl to give it a real good coat of paint.Under the cowl was pretty clean for the most part,but there was some surface rust at the corners.The cowl has seam sealer under the seam.Should I use a sealer under there again?
