About the product
- S100 Engine Brightener can take a tired, grayed-out engine and make it look almost factory-new again
- That factory black look comes back and lasts for miles and miles and holds up to a bunch of washes too
- Just clean the engine and dry, then spray-on S100 Engine Brightener
- Use the handy misting spray nozzle to get into the cooling fins and crannies without over-applying
