Is the PPG primer your using a 2 part (or 2k) primer? If it is you will be fine with not sanding or top coating for a while. A seal is just what the name implies. It seals off the finish that you are going over the top of. You will probably get some different answers from different folks on this, but it has been my experience if you are using a 2k primer you really don't need a sealer. What happen when you apply paint over an unknown finish or a cheap primer is the color actually sinks in. If you have heard the term gloss or color hold out that it what sealer or 2k primer gives you. The new paint without a sealer or 2k primer may be smooth and slick and actually look pretty good in some cases, but it ain't gonna' cut it if you want nice stuff. In the worst examples the color coat will actually lift cheap primer or what ever is under it. I say this a lot but it is true in EVERY case. "Unless you have years and years of experience do exactly what the paint mfg. recomends." Their tech folks are great and they want your paint to come out right. If you do listen to anyone else on any forum remember this. They don't have to come help you when their suggestion fails. Happy painting.
