I have always wanted to find simpler, cleaner, and faster cleanup procedures for 'white painting' your M14/ M1A receiver. I grew up fondling real USGI M14 rifles that were imported for $ 400 back in 1986 or was it 1987?
Don't get old... it's not getting easier. 
So I started out using 'WhiteOut' simply because it was easy to clean up afterwards with Acetone or Nail Polish Remover. Don't tell your wife or daughter that you dug into their stash...
That worked for many years, but sometimes during the cleanup, the excess would run all over the creases and a ghost white image would 'cloud' up the machine marks or the parkerizing etching on the receiver.
Then I really would have a larger clean up job on my hands requiring an old toothbrush and scouring powder/ VIM compounds.
So let's get started:
Prepare the receiver (target area to be "paint filled" )
* Masking tape is your friend
* Use a China Marker in White (artists supply, hobby supply, used car dealership, used car parts supply)
* White Crayon from your kids' coloring crayon collection
Then rub the white crayon, in all FOUR directions to FILL the engraving/stamping.
Make circles ALSO !
Identify the missing spots (corners, tops of letters, interior of letters and numbers)
As you can see, I still have a few corners to fill
Use a rag, cotton works well; rub off all the excess surface white wax/crayon and fill in once again as needed (smaller circles around the gaps)
Clean up, wipe up and admire your work!
In this picture, have a look at the numbering on my NM sight 'barrel' and then the windage knob! Since I was a NRA High Power shooter, I hung around many Americans who seem to enjoy this kind of practice for all their match rifles.
Well, I hope this customization will work for you. It's all good fun!
Cheers and thanks,
Barney
