Dear mid-60s Buick caregivers who dread getting any dings on their pride and joy,
David Conwill has a nicely documented test of a scratch repair kit from Dupli-Color on the Hemming's website:
https://www.hemmings.com/blog/2018/10/02/product-test-dupli-color-scratch-fix-all-in-1/It is mostly likely a more interesting product for modern cars, but it might be suitable for a classic if you can get a kit that matches the paint on your car. As noted in the photos, it definitely isn't an invisible repair, but it is a "wound" that has been healed instead of an utter eye-sore.
FYI, . . . . . Edouard
