perfect gloss

just a question for those of you who have used perfect gloss before.
i had an attempt at using this this weekend and like the finish and the gloss when dried but when i brushed it on it seemed to be too thin, and had lots of air bubbles i then tried again with a thicker layer of perfect gloss poured it on and brushed it to spread and used a heat gun to remove air bubbles which worked great but i seam to have picked up a few particles of dust in the finish. what is the best way of applying i think the dust came from my brush. i was thinking to pour it on and then spread with a spatula

thanks
Matt
