Any idea how to deal with the circular, discolored dings like the one near the SC?
I'll have to look at some of the other spots to see if there's much discoloration/yellowing of the clear coat. If it's still pretty clear, then it's not too hard. I'll put some paint-prep cleaner/degreaser (like Prep-Sol) on a q-tip and try to clean the crack out as much as possible. Applying the degreaser will also show how the ding would look repaired as-is. If it pretty well hides the ding as-is, then I'd just apply some very thin super-glue to the ding, fill the crack, then wet sand and polish.
If there's a bunch of stuff in the crack that won't come out just by cleaning, or if the edges of the clear in the crack itself are discolored, then I'll take an exacto knife and CAREFULLY scrape away the clear in and around the crack until I have all the contaminants or discoloration removed. Then I fill the area with super glue, wet sand, and polish. You have to be very careful not to get into the color coat. Go very slowly, use light pressure, and check your progress by applying degreaser periodically to see how it would look filled.
If there's an overall
yellowing of the clear coat, it's a lot tougher if you have to scrape stuff out of the crack. If you remove the yellowed clear and then replace it with clear super-glue, you run a risk of having a lighter-colored repair area.
There's always the possibility that the repair won't look any better than the crack. Gotta be careful and go slow. Or just decide to live with the ding. On a black guitar, this is a piece of cake. On something really bright like DY, the repairs can be a lot harder to hide.
