So after doing a load of level sanding about a week or so after spraying, I sanded through the back
I managed to get the front levelled off quite nicely but I had to be quite aggressive and use 400 grit to get it all level, which made me think that If I haven't gone through the front yet, there is a strong possibility I will while buffing, so more coats needed. But annoyingly out of lacquer.
So I got this, it's the Earlex 6003 HVLP system and I had a go with it today using Morrells nitro with a splash of thinners.
Practiced on a bit of cardboard first to get the settings on the gun right and then had a go on the axe, the difference in the results I'm getting are night and day. Filmed these short clips about an hour after spraying, got a run to sort out on the front which I'll try scraping/sanding out tomorrow, but I'm confident there is plenty of lacquer on it now, the coverage is far superior and it's gone on and levelled out a lot better than it was out of the can (probably a lot of that is down to poor technique), but much happier
