Koch-Chemie - Motorplast - Naturally Shiny, Water-Displacing Engine Conserver; Restore Appearance; Elastic Protective Film Protects Power Units from Corrosion & Environmental Factors (500 milliliters)

This is best and easiest product to use on the engine . It works very well when doing it the correct way. The product last a while . It is better after cleaning the engine to leave it damp where product gets moved to all the crevices by spraying all over engine bay with a good mist. Little goes a long way . Shut the hood and come back after had time to dry and level any high spots with a microfiber and engine looks like new .

I really like this product. It's shines and cleans the engine and the components well. I do like how it is supposed to chase water out of sensitive components. I believe it does chase the water out because so far I haven't had any problems starting a car after washing and then finishing with this product.First I spray the engine with a degreaser, I then agitate the dirty parts with a brush, then I rinse with a garden hose( most experts say do not use a pressure washer). I then use my leaf blower to dry the engine and everything else under the hood. And finally I use this product to finish.

I have detailed the engine bay on my 35 year old truck many times but the best it has looked since new is with this product. It has been several months now and it still looks great and is much easier to keep clean.

Used on my truck and it works great, looks brand new. Power washed and foamed prior to applying on wet surface and allowing to dry on its own

I use this on every car I wash. Today I used it on my dad's RAV4. Easy peasy.Spray the engine with an APC like GreenStar, then use a wheel brush to agitate. Rinse, then spray this on. Let it dwell while you was the rest of the car. Then wipe any excess of with a microfiber and you're good to go!

Great for cleaning and detailing the whole engine bay. Not too shiny, doesn’t gum up. Restores the plastics back to a nice factory level of sheen.

Good stuff. Works as advertised. I use it in my detailing business

Works very well
