Post subject:  Burn-in lacquer question

I got the kit from StewMac, and did a practice fix on an old Silverstone neck I have. The gouge I made was maybe 1/16" deep and 1/4" x 1/4". The fix went smoothly. I did it all in one shot, since all the instructions I could find didn't indicate otherwise. I over filled it a bit, used the hot knife to smooth it, let it sit for a day, level sanded it, and used about 4-5 coats of aerosol lacquer, a day between coats. After the last coat I let it sit for 10 days. I did the final sanding and buffing and it all looked so pretty.

Then I touched it and it left an impression. What the...? Should I have built up the burn-in a little at a time? Or should I have filled most of the ding with something else (wood dust & super glue?) and just used a thin layer for the burn in? It works pretty slick and looks great, but it'll have to be more durable than that to be useable.

Thanks.

I use burn in fills all the time. I have sticks from stew mac, Behlins and others and have never experienced what you have said. I suspect it is your rattle can lacquer, I used some Watco in a spray can for a small furniture repair and it took weeks before it wouldn't print.

Also, with the burn in sticks there is no need to wait more than a minute or two after filling to sand and finish.

Bill, was your impression a fingerprint? Or more on the order of a dimple in the repaired area? I'm sorry it happened to you, but I'll bet it'll fix pretty easily. Let's see what the rest of the finishers have to say.

At first it was a fingerprint, then I just had to screw with it and I pressed lightly with my thumbnail. It's really soft. It doesn't do it outside of the repair area, where there's new lacquer. I'm gonna check my cans of lacquer ( I got 4 aerosol cans in a starter kit from-who else?- StewMac). If there's a batch number or some such I'll try a different can. If that is what's bad, it'll be the first anything I've gotten bad from them. I wanna get this figured out before I try it on a real guitar.

No, nothing yet. I dug out the lacquer from the first go-round, but haven't gotten to refilling it yet. I should work on that tonight. Thanks for the nudge.

I got to it. It came out fine this time. I don't know what I did, but it didn't happen this time.

Now to get to work on the gigantic ding on the back of my Les Paul's neck. I dropped a nickel in it and I still haven't heard it hit the bottom.
