What work's best on black engines?

+1 S100 is the shiz.

 

Yep. Almost as good as Pig Spit.

 

+ how ever many for the S100 Engine Brightener. Make the cases look new. Easy to use.

 

works great on brake calipers too. just use something to mask off your brake rotors and pads.

 

best I found is Armor-All. It covers any dirt like magic...makes it invisible plus blackens the paint back up too. All You do is spray it all over the motor (frame too if its dirty...don't have to even wash it first)....then wipe off the chrome. Been using it for years in my detail shop. Excellent for covering dirt in fenderwells on cars and trucks.

 

Don't go sideways on me, but if you detail vehicles - aren't you supposed to remove the dirt, not cover it up?

 

Thats what I thought you were supposed to do. Maybe not??!?!?!?!
