A few weeks ago my callipers looked liked this.
I took it apart, degreased it, roughed it up and sprayed it. That took several hours cause I'm pedantic. But then it ended up like this.
Final product.
So doing it took about half a day, 3-4 coats, I also had to do the rears first then take it off the axle stands and then do the fronts because there just wasn't enough axle stands to go around. But it was fun, I got to play with an expensive hair-dryer and I'm pretty sure I've gotten about an extra 20bhp just by doing this.
Why did I bother doing this? Cause I can. Is it possibly the beginnings of me doing stupid shit to my car? I hope not. lol
Took a bit of effort to get this shot.
