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

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.

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.

Was hoping for better results but the product does work.

It makes the engine look new

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

Put it on my 2009 ultra classic Harley Davison the paint on the motor was very faded milky white a few squirts Of the engine brightener and it looks like a brand new motor 1st day people complimented me I didn't say anything to anyone but they told me how the bike looked new looking at the motor

Each can Lasts for 1 year

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
