So for those of you who have after market exhaust or the HKS upgraded exhaust what do you use to keep it clean? My exhaust looked really nice when I first got it and now they're all dirty, so it's time for a cleaning.

Also I need to apply some touch-up paint so I bought some from Lexus. There's two places that need to be touched up, one right on my A-pillar which is a paint chip all the way to the metal, and the other is on my front bumper where there's just a slight rock chip. Last time I tried to use the touch-up paint it seemed to be too liquidly, I was using the brush and when I applied it to the chip on my A-pillar there was a huge blob of paint, and when I tried to wipe some of it away it smeared and got nasty, so I just wiped it all away. Then when I tried to apply some to the front bumper it all just ran down as soon as I applied it. Any good tips or techniques for using the touch-up paint? And do you think I'll have to take my front bumper off in order to paint it properly?

 

I clean it like the rest of the car ,with shampoooooo
