Was able to get my girth belt all set on this snowy day.
I used rustoleum colonial red latex paint mixed with some water based brown wood stain to get the color, then mixed in water until I got a milky consistency.
I then poured the paint into a roller pan and dunked the belt into the paint to completely saturate all of the rope, working the paint in with my hands and a cheap throw away paint brush.
This is a really messy task so gloves and plenty of paper towels are a must lol. After getting all the rope completely soaked in paint I "rung" out the belt to remove any excess.
After removing the majority of the paint by hand I tried to remove as much paint from the buckles with a rag. Then I hung up the belt from both sides with a hanger to make a hammock and let the belt dry for 48 hours.
After the belt was completely dry I worked the ropes to remove any stiffness in the belt. I also used a rag and some 91% IPA to remove the remaining paint from the buckles. I then went over the buckles with a wire brush to give them a duller appearance.
After all of that I sewed on some black 1" webbing and added some holes to the webbing with a soldering iron.
I think it came out pretty well, the paint seems to have stained the belt nicely as well as stiffen it up. I followed a tutorial on here that illustrated a similar method. Going to let it dry and work the rope more before I wear it against my flightsuit but I haven't had any issues against a t shirt so far.
