As nobody had any input I decided to go it alone! I used a soy based chemical stripper to remove the old finish. After stripping it was revealed that a previous "restorer" had sanded through the veneer at the edges of the speaker grill!
I then applied two coats of stain by General Finishes which I bought at Rockler. The color was American Walnut which is a perfect match for the original color present on the untouched original dash bow wood.
Following the stain, I applied three coats of outdoor oil which is an oil based clear finish fortified with UV resistant compounds, also made by General Finishes. I chose an oil because it allows the wood grain to show while giving a matte to satin finish. I sanded between coats with 320 grit sandpaper. Despite all this effort, the area where the veneer was sanded off looked darker and unsightly. I decided to fix it by using artists oil paints and a fine brush to replicate the grain and color of the missing veneer. When the paint dries I will apply as many more coats of the outdoor oil until the final finish and sheen is correct.
