S100 19200A Engine Brightener Aerosol - 4.5 oz, red blue

Brings black color back to life.

I ride a 2009 Harley Nightster with grey motor,I cleaned the bad spots with windex first then used this product.Looked like new.

Great product. Very easy to use. And Great shine

Great product

This engine brighter for black engines is amazing! It is not as messy as I was expecting it to be and absorbs nicely with mild overstay that's easy to clean. I used about 70% of the can but got all my engine and cases and it is nice rich black again and no longer grey. I'm buying more! Also, highly recommend doing a full washing of your bike beforehand and Bike Brite is a great soap to use for all paint types even denim paint. That bike brite was a great cleaning agent on my entire bike but also for my engine and got rid of oil stains and once dry I sprayed the s100 and it just was the perfect finishing touch! I wish I had day time photos of the finished wash of my bike but forgot to take picture right after but I put these night time pictures up anyway so you can see my bike.

It's been around for a long while now. Why? because it just flat out works great that's why. Buy it you won't be disappointed .

It does an amazing job on my older Harley-Davidson and my newer one .

Have an older Harley with the wrinkle black engine paint. one 4.5oz container was good for one use and the results were amazing and all of the "Ashy / grey areas of the engine are now black and shiny, the black looks brand new no joke. just clean and then once dry spray with this product and let dry. will buy again ( have heard that this lasts 1 season )
