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

was super easy to use, just washed my bike completely, blew it dry with a compressor, then applied S100 to it and wow it made a huge difference, especially after i hit the engine with touch up paint beforehand too. Works on lots of parts, I put it mostly on the engine area though. I’ll attach a before and after for my 1982 CB900

S100 19200A Engine Brightener Aerosol - 4.5 oz I’ve been using this stuff since the early 2000s on multiple Harleys with black engines, and it still works as good as ever. It puts a nice, even shine on the motor and gets rid of that dull, chalky look. Works great not just on the engine, but also on textured black parts—rubber hoses, connectors, and wire looms all clean up and look refreshed. The key is not to overdo it. If you spray it on too heavy, it can stay wet and actually attract dirt. Best results come from a couple light coats. I usually warm the engine up first, shut it off, apply lightly, and wipe down any obvious wet spots. Done right, it makes everything look clean and dialed in. If you’ve got a blacked-out engine or faded components, this is a go-to. Bring the Black Back.

worked better than expected! My bike was a neglected surplus police bike. after repairing the needed mechanical needs,it was time to start detailing. I was skeptical but after using some of S100 other products Iknew they had som quality products. If you are looking for showroom looks on a very rough bike this is not a magic wand. however if you are looking for a much needed upgrade in appearence this product will do just that. follow the instructions and I believe you will like what you see.

Excellent product. Makes my engine bay shine.

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.

Used S100 Engine Brightener on my HD. As a professional detailer, and with my bike being garage kept, meticulously maintained, and already in great condition I saw dramatic results. It’s a small can, so use it sparingly. A little goes a long way, you’ll get about three uses out of it. That said, it definitely gave some of the faded areas a nice little boost. I’d purchase it again when detailing on other motorcycles. Pro tip: CLEAN YOUR BIKE FIRST. Also, when wiping off any excess product reuse that same rag on other areas like faded plastic trim. It can help restore a deeper, darker finish without needing additional product.

This stuff works well . It’s not gonna polish a turd but it will “brighten “ your black krinckle for sure . Good spray cap for east use

Much cheaper than Harley dealer and works great

Each can Lasts for 1 year

منتج رائع واكثر استخدمته لدراجتي هارلي محرك اسود لمعان واضح جدا انصح وبشده عيبه العبوه صغيره الحجم والسعر نسبياً عالي

This is good stuff to spray on your engine after cleaning. Makes the motor look new

The quantity is quite less for the cost although the product is great. Tried it on my iron 883 engine and looks brand new. Lasts for quite a while.

Good stuff
