Say I wanted to remove the superficial laser engraving on a standard AR lower receiver - would alumablack work? Anyone ever tried? This isn’t removing the identification marks on the gun or anything, but I’d like to get rid of some laser engraving like you would get out of a low-power trophy shop laser, or like you see on “custom” lower artwork. Basically it’s just through the surface finish.
If I use alumablack, is it going to be blotchy or discolored? Anyone have a better idea? I could dura/ceramacoat/moly it but I’d prefer to just darken the light engraving.
I’ve covered up the laser etching on flashlights with nothing more than a black sharpie. It doesn’t look perfect but it cuts the bling, and you can always wipe it off again with some solvent.
don’t know if this will work, but i’ll be trying it myself on a project- chemically strip the engraving and soak in concentrated rit dye.
colored aluminum is not much more than dying aluminum oxide, since hardcoating aluminum turns it black. therefor, i predict the aluminum oxide of the engraving (aluminum reacts with air to create a thin layer of aluminum oxide after exposed for a couple days) will accept an aggressive dye
We had a customer that wanted to remove the spiders off a set of spikes tactical . We soaked a cotton ball in aluma black and let it sit on the area then rubbed the engraving with the cotten ball it took repeated times but they did get black and disappear seems the trick is to let it sit on the area . I would at least give it a try
That’s right. They have them on amazon. Used to use those to freshen the engraving marks on old cameras (when cameras were worth working on, like 1930s Leicas). Surprised they still make it but I looked and there they were.
These were done using BC Alumablack.
H1 Aimpoint logo did good.
BCM logo on upper only darkened enough to subdue it a bit. The flash makes it appear lighter than it is.
Should be able to find them at ACE, True Value, Mcmaster-carr, Grainger, etc…Not sure about HD or Lowe’s but Harbor Freight MIGHT carry it. I used it ALL the time in mil acft work…It works and it’s laquer–and what a buck or two per stick?
So far I’ve degreased and tried a black sharpie, which works pretty good but isn’t durable. After playing around with it, I used some solvent and removed all the sharpie and then tried a Birchwood Casey paint pen I had. It didn’t work as well as the sharpie.
I don’t have a lacquer stick, but I think those work better for engraving that has depth. Since there’s nothing to fill in here, I don’t know if a lacquer stick would work so well.
