You can find the grabber green paint in o'rileys / Auto zone. I'd suggest sanding down the grain to give it a lot smoother look. Sand down 400 grit to take off the grain. Then hit it with 600, 1000, paint color, went sand 1500 paint, clear. You can take it a step further and do 3000 grit / polish but I never went to that extent. Here are some pics of what I have done so far. I actually am in the process of painting the letters in the coil covers right now. Bout to go out and sand it some more and clear.
I originally did mine in grabber blue but decided to change it up because everybody has it. Here I also just painted the color and no sanding.
Then I decided to go red and take it a step further to sand off the grain.
Here is a cruddy shot of Justin's grabber green I did. I'm sure he has better pics.
