I am currently doing a new construction exterior... I have decided to use Aura on all trim which is pre-primed....The color is tre-moss, probably about a 2base, 1 coat did not cover and it 100% needed a second coat..As far as it being self-priming, being that it says to spot prime all nail holes,it really isn't cost effecient when doing new constuction..The time it takes to do that it is much easier to prime entire surface then top coat with Aura...The only reason that i may want to use this product over another is for color retention and dry time, but i can't come to a conclusion until it has been tested over a peroid of time!!!
