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

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.

Much cheaper than Harley dealer and works great

It looks great on the black engine. It has given a very glossy, almost wet look. I will have to see how long the shine will last and whether it will attract more dust. Just be careful not to get it on parts that you don't want slippery. The quantity is not much but if the original engine paint condition is not too bad, you may be able to get away with less spray. For example, I used a wipe to smooth it out on the engine, and that piece of wipe worked on other parts without additional spray.

Good product.

Muy bueno pero recomiendo comprar dos latas yo tengo una street bob harley davidson 2011 y use 2 latas para motor y acabados

Harley owners, if you have a black motor, this is a must have product. If you are not aware of how this works, this will make your motor look brand new with a little shiny gloss to it. I highly recommend using this. I’ve been using it for years and will continue to use it as long as I’m riding.

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.

Great results. Small can. For some reason I expected like a normal paint can size but it's about half that size. I will probably buy again

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
