I'm in the process of repairing a bar ding that is on the edge.The finish cracked, and shelled off about a 1/4"X 1/2" place. Dupli Color has clear in the touchup bottle where the paint colors are, looks like it is going to work out OK.
An FYI that I thought I would pass on...Bill

Try the Dupli-color on a small spot underneath the guitar first. See if you like it and it isn't too thin. A good grade of clear nail polish works good. It's real nitro lacquer and it is thickened. It won't run all over the place.
Start by laying down a few drops of lacquer on one side of the chip. After it is dry, lay down a few drops on the other side of the chip. This process is called "dropping in" by guitar repairmen. When you have filled the chip with lacquer, let it dry for a week and then sand it flat with 600 grit or finer wet sandpaper. Look for any spot that aren't filled, and start the process over again until everything is level. Polish with polishing compound.

Glenn,
That's what I'm doing, I have the place filled and will let it cure for a couple days then sand level with the original finish. I am going to try to fashion a tool/jig to sand to proper level then change to 1000 grit and polish. The way it is now it's hardly visible til you rub your finger across it. I will post a picture of the tool if it works like I think it will.The viscosity is ideal for this type of repair.

| Bill, if the chip was on the edge this might not work but it is a valuable bit of information. Take a single edge razor blade and put a piece of "Scotch" tape on each end of the blade. The tape will keep the blade from cutting too deep, then scrape with the exposed part of the blade the top off of the lacquer until it is level. The lacquer will remain the thickness of the tape higher than the finish, then wrap a coin (quarter) in a polishing cloth and block rub with compound using the quarter as a "leveling block" as in block sanding. |

Jerry, That is basically what I had planned, but with 600/1000 wet paper, and polishing compound. Eastwood sells a device to remove drips/runs in paint, is where I was basing my process. I don't know if a blade will cover enough area, I had thought of a strip of metal with tape on each end, and sandpaper (one wrap)in the center, as per the blade process. Looks like it has melted in pretty good, may have to do another coat.

Bill,
Try the tinyest bit of Dupli-Color green to fix the color, then put the lacquer over top. Eastwood's run shaver is probably over-kill for this job. You want a hard foam or cork block behind the sandpaper. They sell them for a couple of bucks in the Paint section of the auto parts stores.
Sand wet for a minute and then let the lacquer harden again overnight. Nail polish is more solvent than it is lacquer, so the more time you let it cure, the better your repair will be.
Good Luck!
Glenn
