Yeah, as Sunsanvil says, straight from the bottle, higher airpressure than normal.

It was once thought that the Model Air Varnishes were pre-thinned like the rest of the Model Air line, however Alex Vallejo himself set me straight when I complained that they were discontinuing the varnishes in the Model Air line.

He told me that the varnishes in the Model Color line were infact the same product....now I know the rest of the story! LOL
