I really had a surprise with this lower valance. I thought it had just been hit and pushed in but when I cut it out, I found that it had been badly damaged and someone had just piled on some filler and smoothed it out. The valance was actually badly wrinkled. So I bought a Planishing Hammer at Harbor Freight and after some practice on some scrap, went to work on the mangled valance. I must say, I was very pleased with the outcome.
