Before the 2015 driving season was to start, I decided to refinish the dash in my TR, as well as finally replace the top pad of my dash area. The dash itself had a little sun and water damage, and frankly I had not really finished it correctly in the first place. The top dash panel itself had released from the scuttle and from under the windshield frame and it was curling up. It looked terrible!
To re-do the dash panel, I had to remove all the instruments and separate the panel from the car.
From there, I block sanded the panel with 320 grit paper. This process took quite a while as I wanted to take it down past the sun/water damaged areas. Next up, I used Birchwood Casey Tru-Oil Gunstock finish to finish the dash panel. The way I did this was by using progressively finer grits of paper and 'wet-sanding' the dash. The lubricant for each grade of paper was the Tru-Oil itself.
My process was to put a drop of Tru-Oil on the dash, sand in small circles with the paper, then wipe the slurry off the board, across the grain so that I would push it into the grain and fill it. I did this 4-5 times with the 400 grit paper and 2-3 times with the 600 grit paper. Finally, I used 1000 grit, 1200, 1500, 2000 and 3000 grit paper.
Finally, I 'French polished' the dash with straight Tru-Oil with a little cotton buff. After letting this sit for a week, I buffed this out with a microfiber towel and Meguiars plastic polish. I chose the plastic polish because it is very gentle.
The results are wonderful!
