      A while back, I believe on facebook, I saw that someone had used black super glue to fill the seams on an airliner model, stating that it was easier to see, and also easier to sand.

      Does anyone have any info on using black super glue; is it easier to sand, or does it have any other properties that would make it worth using?

      Hi Gene -- the black superglue contains quite a lot of rubber. It came out about a decade ago, and I first used it five or six years ago. Incidentally, quite a lot of superglues contain rubber, and many of them are not black in colour -- I have one that is mid-dark grey and have seen reddish ones and even clear-to-pale-yellowish ones. Apart from the inevitable overspill being easier to sand and shave away, it has no particular breakthrough virtues over, say, gel superglue. It smells odd, probably fogs clear parts, and still get your fingers covered for days and days (but now they look nice and colourful )

      Best,
      Peter

      Thanks Peter! Since there is rubber in it, does it still sand smoothly, or does it want to ball up as you sand it?

      Yes, it sands wonderfully well to a feather. Doesn't really crumble. I suppose it might form tiny flints under _very_ energetic sanding, but, personally, that's a lot better than the unyielding, glass-hard properties of old superglue! As usual, apply a half the amount you think will do the job and take it from there
