engraving

I came accross this little machine while looking for information on engraving some of my personal firearms. At $80, it pays for itself in as little as 2 engravings of your name and address on firearms. They also say you can email them custom drawings to get stencils if you don't want to shell out the extra cash for the stencil machine.

For metal bodies I have a good one.

Uni-PAINT markers, anyone that's been to a junk yard knows what i mean, they mark on anything. pick up an oil based paint pen anywhere you want in whatever colour.

get it flowing good, dab it over the area you want to fill. wipe away excess paint with a dry cloth. let the rest dry.

I used rubbing alcohol to remove the excess paint, it won't hurt the body, or the stock paint.

wipe lightly to remove the surface paint, looks great :D

If you want a temporary solution, use a white wax crayon, easy to go on !

you can do, what we use in miniatures, like Warhammer, is INK, it's like paint but more liquid, then you just apply the paint all over the spot, and wipe off gently the excess

a cheaper alternative, use those liquid white correction fluid.

dab a small amount on the markings, wait a few minutes to dry, then wipe of the excess with a wet cloth. correction fluids are mostly water soluble.

i painted the engraved markings on my C.A. lower receiver, hasn't faded a bit even after a year.

I did a colourfill on my full metal rifle. Due to the stamping not being deep I did try using crayons but it looked like garbage and wouldn't fill right since just too shallow. I ended up watching a vid on youtube where the guy used nail polish so I tried that method. Worked out way better and was very simple. Items needed was red nail polish, white nail polish, non-acetone nail polish remover and cotton pads. These are all things if you have a girlfriend or a wife they will probably have on hand.

Process was simple, paint over the logo you want done, let dry for over 25 minutes, put some non acetone nail polish remover on a cotton pad and lightly wipe. As you go it will remove excess. From my understanding this will work on polymer as well.

In the picture comparing both crayon is on left and nail polish is on right. Also note on the right panel that was right after it was done so still was wet a bit. There was no damage to the metal as you can see in the first picture :)

I used a whiteout pen and wiped off the excess with a cloth and alcohol. Do two coats, and let it dry fully between coats for best results
