Two things about Polyester

There's a lot to know about polyester primer, but two important ones are this:

  • The first coat should be barely medium, not wet.  Also, not dry. It adheres better if it isn't sprayed wet on the first coat. 
  • Walk the car.  Don't spray each panel by itself. (Assuming the car is assembled). This prevents double coating the edge of each panel. That's a lot of extra polyester to block down.

  • Which polyester primer do you recommend? I have friends that use it on fiberglass or smc. Not so much on metal.
