I'd like to use the Zinsser spray shellac can for a project I'm working on (ie, the can Zinsser sells with the spray nozzle). I've brushed and also padded shellac before and have a feel for how much shellac to apply, based on feel/tackiness. But I tried spraying on some test pieces and have no feel for how much to spray on in one application since there is no tactile feedback. Do I keep spraying until everything looks wet, or just try to cover the surface lightly and apply several coats? Is it necessary to sand between coats at all or just after the final spraying? I should mention that I'm applying shellac as a sealer coat after dying with a water-based dye, and before applying an oil based glaze (BLO + gel varnish + oil-based artist's colors) and oil-based varnish as a topcoat.
