These products are going to be released into the USA market for 2011 (not sure if I can say that but the cat is out the bag...

)
Expect a small packaging change (along the lines of the new Odor Eliminator G2316) but the formula will remain unchanged on both.
What makes the Engine Cleaner a little more special than most is that although a powerful degreaser and grime stripper, it is not caustic and will not cause aluminium and other metal parts to stain white like most degreasers will. For the most part, even agitation is not necessary but an HP for rinsing is recommeded as it significantly reduces the amount of water being "applied" into the engine bay.
The Engine Dressing can be likened to our G41 Natural Shine in many ways, but with a much higher tolerance for heat.
