This signal box was printed in Frosted Ultra Detail to see how the finish would look. As the box is made up of parallel boards and has corrugated iron on the roof at a slope I think that this gave the printers a challenge as there are fine print lines inside the box and on the rear wall at about 45 degrees. I suspect if the box was printed as it stands in the landscape then there may be print lines visible in the corrugated iron but this is not the case due I guess to the 45 degree print orientation.
I found that unusually the Frosted Ultra Detail had a slightly rough surface which I think was due to the waxy support material that is used in the printing process to support the 45 degree angle when printed. I cleaned the box in acetone then painted it without any attempt to remove the roughness to see what it would look like. It didn't look too good so I then scrapped the surface with the flat edge of a jewellers screw driver which reduced the roughness. I think that a bit of judicious smoothing with some fine wet and dry paper would also be beneficial.
Here are a couple of photos that show the roughness prior to the scraping.
