I know that ReRanch has it but by the time you add their minimum shipping its $40 for a couple of ounces. I don't need much but there must be a better source!
How big of an area are you touching up? Reranch makes touch up pens that cost less than the spray cans. And the shipping on those is cheaper as well. Guitar ReRanch Touch Up Pens There are a few paint brands you can find in big box hardware or auto parts stores that are close to LPB, but exact matching is tricky. What kind of instrument are you touching up?
The problem is not everyone's "Lake Placid Blue" is the same. But those pens is probably your best bet.
So the touch up is really where paint has chipped off around the pickguard screw holes leaving a little exposed white primer. Its a custom '54 PBass and Matt Jenny did the body and said get touch up from Guitar Reranch. I've decided to go without a pickguard and am installing a racing stripe - not worried about the pickguard holes being filled and finished, just the edges of the holes so they don't look like small white spots. 10 or 12 drops of paint is all I need. Their website says the shipping minimum charge is $12.75 but they are shut down for a few days so I'll inquire when they are open.
I ordered 3 touch up pens and shipping was $7.90 which was fine with me. Pens are quality with a bb (maybe) agitator inside.
By the looks of the OP’s ax it’s the middle guitar. Guess the most common LPB? But the color from the touch up pen could vary a tad.
Bumping this because ReRanch is currently closed. I have a couple chips on my American Performer Precision and would love to get it fixed.
Well, you could try the nail polish trick. Take your bass to a cosmetics counter (if you can find one that's open) and see if they have a blue (or whatever they are calling it, "babydoll blue mist" perchance?) nail polish that's close enough, might get lucky. Most nail polish is just nitro laquer. I've done it with Fender Wine Red on small chips, and it was a damn good match.
Call Mary Kay Cosmetics and ask them to send a nail polish sales rep to your home. Get plenty of samples in case you buy another bass.
