Not sure if anyone has posted this before, but here it is;
I have been testing some primers that you can find a Wal-Mart, K-mart and home centers. I've been getting tired of paying almost 5 dollars for a small can of primer so I picked up a can of Rust-Oleum Painters Touch sandable primer and have been testing it on some old kits parts.
Well this stuff works great, it drys within 15 minutes and shrinks on to the plastic and can be wet/dry sanded with no problems. I would compare it to the Tamiya primer which i like. But Tamiya's primer is $ 5.00 for a 6 oz can while the R/O is $4.50 for a 12oz can. The only thing is, the R/O grey is a bit darker than the Tamiya's. Next time I hit Home Depot I am going to see if they have White primer.
Hope this is helpfull.
