So I decided to accept the minor defects in the metallic colour coat because I didn't want to repaint again.
So bindings are now scraped.
Another lesson learnt....never again will I freely choose to build a guitar with binding. Pain in the ass and couldn't get it to look as good as I wanted on the top.
Now I'll spray the clear coat when I get a chance. Will just need to run over the body with a tack cloth or something to minimise the surface contaminants.
