Once again, a vast amount of sanding. Fortunately though, the micro sands down substantially easier than the flox.
Once all was sanded to shape, I shot a thin layer of grey rattlre can primer and left that to dry. I then wet sanded the primer (400 grit) until it was so thin it may as will not be there. The nett result though is that the primer has now filled all the tiny little nicks and scratches that were conpletely invisible before.
I then shot another very light layer of primer and left it to dry.
Sanded down with a coat of primer
Primer wet sanded - all scratches, etc from previous sanding now filled with primer
A very light coat of primer to try and find any more "blemishes"
