Looking for epoxy resin recommendations

So im a bit desperate to finish a sign i’m working on (full story here)

My intent was to do a shallow flood of resin around the name section, primarily driven by the fact something got messed up and the bit ran deep just below the W and around part of the first Y next to that W. Since i’m not confident about using the resin for the first time on a sign that’s almost done and needs to ship by Monday, i’m thinking i just use the resin to fill the deep cut from the bit. Thinking this might be easier to fill and get level vs trying to fill it with filler/bondo and then sanding and such.

So what resin can i find at Home Depot or Hobby Lobby that would work well? I’ll also need some tints that will work as i need to make a teal color.
