I've never used any of the Evercoat products (and gererally distrust any product that uses a K where it ought to have a C) but I think if you are trying to repair chips in gelcoat that what you need is something more like a gelcoat repair paste that liquid gelcoat.
I've used the gelcoat repair kits from Spectrum Color
on my Whaler with some success. Their claim to fame is pre-matched color for a bunch of different production boats. The repair kits have a 2 oz jar of gelcoat thickened into a paste which does a nice job of filling chips where you have some depth.
Gelcoat needs to be protected from air in order to harden correctly and the standard approach is to either add a special 'wax' to the liquid gelcoat or to spray PVA stuff over it... but these kits come with all the right stuff premixed.
Another option is to use white Marine-Tex. Trowel it into the chip and then tape some plastic wrap tightly over it while it hardens. But you may find your boat is not the same white as the Marine-Tex - or even the evercoat gelcoat you are using now. Not all white boats are really white...
Actually, the plastic wrap trick will work with the gelcoat paste also.
What I do is mask off the repair with some very thin tape, fill the chip or gouge and then tape the plastic wrap over the repair and use my finger to try and smooth it out. The plastic wrap gives the repair a smoother finish.
You will end up with a little extra thickness (of the tape you used to mask) and if you are trying to go for perfection you can wet sand with 600, 1200 and then buff and wax to make it even and shiny.
Even if you don't use Spectrum's products, you might have a look at some of their instruction pages
