I ordered a gallon of the MGHD. It's the only engine dressing I have not tried. After reading most of the reviews about it, I think it will be my go to for engine bay and exterior plastic trim. 303 and Sonus Motorkote are the other products I've been using over the last several years. Both work well, but I like that I can use MGHD on everything and the way it lays on surfaces. Additionally you can dilute it to different ratios. I know the durability is not on par with Sonus or 303, but it should be good enough. Honestly, I never felt any of the products I've used last or "condition" as well as they claim. Therefore it becomes a matter of what is the easiest to use and still look great.

The one question I had is how to apply it to the engine. Do you spray it on after you clean/rinse the engine while it is still wet? Or do you dry it, then apply it?

Thanks
