Actually I have to disagree with this .  I have found that it is
necessary to coat all the color coats on a given piece on the same day
with Enduro.  If the product is allowed to fully crosslink between coats
you will see the layers when you cut it down flat during the rub out
process. As for the orange peel,  sanding takes care of that.    I
generally put four to six coats on consecutively,  allowing the previous
coat only enough drying time the prevent sagging on vertical surfaces.

Other than the need to be organized on spray days,  I love the stuff. 
It's cut my refinishing time down to where I almost don't mind having to
do it.
