Dale - As you can see there are a number of products that can be used to fill low spots on a painted substrate. Some of your decision should be based on how extensive the areas are and how easy it will be to sand the areas. I've filled a good number of chipped paint areas on plates, but I have to admit, never on one so ugly as the one pictured in Ron N's post! That being said, I've had my best success with (you guess it!) West System Epoxy thickened with their #410 Microlight Low-Density filler. I used to use their #407 Microballon Low-Density filler, but the #410 is easier to sand - and I mean it REALLY sands easily - very good for fairing piano plates.
