Removing RejeX while it's wet and/or not allowing it to cure will probably shorten its lifespan significantly. If you wipe it off while it's still wet, to a large part you're just wiping off everything you just applied without leaving much of a protective shield behind.
We have found that about 15 minutes of dwell time to allow the product to dry and haze up is about ideal. So unlike traditional waxes that tell you to do small sections at a time, with RejeX, you actually want to do relatively large sections for ideal longevity.
So on a typical sports car, I might start at the front smearing RejeX out as far as it will go and still leave a solid haze on everything I want to treat. In about 15 minutes, I can easily cover half a sports car or more. Then, I go back with a clean, soft rag and wipe it off. At the point the car is gleaming like made and is super smooth to the touch.
At that point, I go park it somewhere safe (i.e. where tree sap, mud and minerals from sprinklers and other contaminants won't get on it for 8-12 hours).
