I could use some advice on the best way to finish a project in flight. 7 days ago, I was painting but I ran out of basecoat after 2 coats. Based on how coverage went with my Omni Plus I think it will require 2 more coats (so much for saving money with a cheaper paint). I have purchased more basecoat but given 7 days have passed, what is the best way to prep the 2 existing coats of base to accept two more? I was thinking to scuff it all with 800 grit. Is wet or dry better or personal preference?

Thanks for the advice.

The Omni Technical Data sheet should have the information you are looking for.
I used Omni one time and that was a very long time ago.
