I think the main reason Your seeing Rust so soon Is it was Never realy Gone to start with. If you dont Use some kind Of metal Prep Once you hit bare metal You'll Never stop The rust from returning NO Matter What Primers You USE in the first place. I have had cars Sit in Lacquer primer for yrs and never seen that happen. but yes Lacquer is more prone to show rust be for anyother primers that I know of. Because It does Not seal as well. The lacquer primer doesn't have as much sealing propertys as enamel Or the Epoxy primers Or a Sealer primer. If you want to stay with the Lacquer Primer Use a sealer as well.
Also a note If your down to bare metal Use some type of Metal Prep that has a zinc phosphate to it This Helps keep the rust from comming Back even if it doesn't have any primer on it for a while. It also Helps In welding. Hope this helps answer your question a little better. }[oooooo]
