I've been soaking my Gibson truss rod cover in coffee grounds and water for twelve hours now with no visible difference. I know people have done this in the past, but what is the secret?
It is pretty muck just grounds and water. I put the mixture in the microwave for a minute so it is pretty saturated. There is really no change after almost 24 hours. I was told by someone to put some alcohol in the mixtire to soften the plastic. All I have in the house is vodka and I don't think that will work.
We always had really hit-or-miss success with coffee in our shop. Sometimes it would work overnight and other time we'd leave something in there for days with no luck.
use earl grey tea, make the tea with the boiling water and wait just a little while, do not take the tea bags out but once it has cool just a little put the truss rod cover in and leave it for just a little while. if you don't get enough color, take the truss rod cover out and nuke the tea. it only took me a few hours to get pickup covers aged nicely
Sometimes, no matter what you do, the color doesn't adhere to the plastic.
I've had the best luck by removing the shiny-ness? by scouring it with Comet on a sock, so it dulls the white plastic. Then, use shoe polish, with maybe a bit of yellow curry powder mixed in.
I brewed some coffee this morning and dropped it in...OOPS!! Now its all melted and warped. :smack: Looks like I'm going to have to buy a new one anyway. Oh well.
