Polyurethane varnish has been applied to the veneer. I think it was
seven coats in total which I applied using a small compressor and
gravity feed gun. It took a lot of effort to get the finish to the
desired mirror quality gloss. The last three coats were all supposed to
be final coats but as I was spraying outside, I was plagued by dust and
flying critters landing on the wet surface. I ended up getting up
really early when the air was still, not a breath of wind and the flies
had not got out of bed. This did the trick and I got a good final coat.
I rubbed the surface between coats with 1200 grit used wet, its
important to use a sanding block if you want flat reflections, you
won't get this using just your fingers. I took the shot outside and
that's a telegraph pole you can see reflected on the right. I let the
varnish have at least three days drying time between each rub down and
re-coat and a week for the final coat to harden before assembly.
