Muy caro, pero sin duda es el mejor producto para el cuidado del motor

Koch Chemie Motor Plast is hands down the best engine bay dressing I’ve used. After cleaning my engine bay, a quick application of Motor Plast leaves all the plastics, hoses, and rubber parts looking brand new. It gives a nice satin finish — not too shiny or greasy — which makes everything look OEM fresh. I love that it dries to the touch and doesn’t attract dust, which keeps the bay looking clean much longer. The product is also heat-resistant, so I don’t have to worry about it evaporating or leaving streaks once the engine warms up. Application is super easy — just spray it on evenly and let it self-level. The results are professional-grade with minimal effort. If you take pride in your engine bay or prep cars for shows or customers, Motor Plast is an absolute must-have.

I saw the Koch Chemie Motorplast & Green Star Universal Cleaner being used on an engine by Pan The Organizer. I also read the reviews (good & bad) of these products on Amazon & ordered both products for my 4yr old Subaru that had caked dirt in places (Have never previously cleaned any car engine). I started with the GS Cleaner 1:5, let it sit for a while then did a quick pressure wash with foam canon followed by quick pressure wash rinse. I left the engine wet then applied about 15 sprays of the Motorplast over every part of the engine, engine bay sides & anywhere I saw black plastic. 15 sprays was overkill but I left it going milky with the water & closed the bonnet. It was a hot sunny day & left it all day. When I opened the bonnet the result was better than expected, exactly like everyone's after pictures. The black plastic inlet manifold, radiator & engine hoses looked brand new. I ran my finger over a lot of areas like fuse cover, hoses etc & surprised it wasn't greasy. Very dry to the touch so will stay clean for a good while. The car doesn't get garaged & has been driven in heavy rain & some dirt roads in the 4 weeks since I cleaned the engine & it looks the same as the day it was cleaned.

Smells great. Make sure the engine is cleaned first.
