priming + sanding question

[dgdarien]

okay okay, so i'm still new at this. and i just put on the first layer of primer on the model body. and i read in Guiddy's WRX post that the primer needs atleast 24 hours to dry.

does the primer need 24 hours between each coats to dry? or does it mean after the final layer of primer has been applied to wait 24 hours. also do i sand after each layer of primer? thanks guys!

Leave it for 24 hours after the last layer before sanding. Leave it for a couple of hours at least between each coat, though. If you do thin layers, they'll dry quicker!

Also do I sand after each layer of primer?

No. Only sand after the last coat or you'll get dust trapped in the next layer. Again, if you do it in thin layers, there should be no real need to sand between layers...
