I take this to mean the top coats will be applied over the previous coats of SM and Grey Primer not the unpainted front of the acrylic sheet.
I have small sheet 2' x 2' of acrylic sheet, some left over SM, white, kilz2, spray equipment etc.. may give this a prototype test. Just want to be sure I have it right.
Nope. You only apply Top Coat to Silver when using a Wall or solid board
Heres the order.
Sray at least two coats of SM on one side, then follow up with a coating of the closely matching Grey primer on top of the Silver metallic. This greatly assists the SM in doing it's job, and negates the need to use even more SM.
Reverse the sheet and apply the Top coat to the oppisite side.
There should be the Back coat of SM, a sandwich of Plexi, and a top coat on the , well...., the top.
Be sure to set you gun to max fluid release, and at as high a pressure as possible. (60Lbs max.) Both paints are very thick. If your gun has a filter inside the delivery tube, expect to have to stop and rinse it a couple times or so during each coating. And strain the paint to remove any coagulated clumps.
I personally would remove the filter if you strain the paints, at least for the first coat.
Lastly, if you don't have a separate Regulator/Water filter in line, I'd get & use one before attempting any large project. And drain the air tank, under pressure, via it's shuttlecock valve to purge any existing water and rust residue.
All precautions help when spraying. Leave the "Fish Eyes" to the ones on CMRA's posts.
