I didn't have any sand paper with all the grits as need to do what I needed to do by hand like I would on the supra or anything else...
Of course I took it out to the detailing department spray some degreaser and some acid on the cover to get it clean and free of oils.
Took a pressure washer to it for a bit. Then allowed it to dry..
Took my rolo disc to it. Medium, then fine and then went to town.
I did tape off things cut out the letters and sprayed them. I didnt like the finished look so then I went in the parts dept. grabbed some touch up paint with brushes and went to work.
Actually used some metallic maroon paint for the lines that matched the color of the car well. lol The V6 normally would be red but I figured to paint it black too because it looked good.
For the center section the auto parts store sent me VHT ceramic high heat paint. Its a flat black but matched nicely I believe.
Now if you want the nitty gritty on polishing to a mirror finish I can post up how to do that if ya want just let me know.
edit: btw the rolo disc leaves almost a brushed aluminum look just not so brushed. Doesn't look to bad imo but could be better.
I almost decided to put right as it ridges down in the front a new chrome 2.5 emblem on it but didnt want to look too busy on the valve cover.
