Question about sealer

Treat sealer as the first coat in you final paint. (Option # 1 above) So, spray sealer, wait the appropriate ammount of time as detailed by the sealer manufacturer, then spray you subsequent paint and clear. Most sealers can be top coated in 20 minutes to an hour, but always follow the data sheets put out by the manufacturer.
What product brands are you using from sealer to topcoat? Are you using an actual single purpose sealer, or a reduced epoxy primer?
Good luck, and don't forget the pictures!! :)
