the pinholes(fisheyes) may be causes by a contaminant on the surface of the primer coat. silicone i usually the main cause but it may as simple as not cleaning the surface with a quality wax and grease removing solvent.
check with your paint supplier as to which one is recommended for the brand of paint you are using.
before resanding, wash the panels down with the solvent.
ensure that you remove anything that may have come into contact with any form of ARMORAL (PURE SILICONE) from your work and spray area.
sand down panels and wash with solvent prior to wiping with a tack rag.
hope this helps

Of course you CAN, but they will separate before you begin to apply them if it's a really fast setting enamel. The acrylic will run down over the enamel.
If you are painting a residence the chances are your enamel is a water borne acrylic enamel. Conversely, if you are referring to acrylic and enamel spray cans then the answer is yes you can spray one to another without any problems. Always be sure your paint is completely dry before applying successive coats.
No, you can't.
Yes, you can.
If the Enamel is an original baked finish there should be no problem. Many DIY touch up paints are made from Acrylic Lacquer. If however the enamel is air-dried then the solvents in the lacquer will react and cause the enamel to bubble and craze. Enamel paints become hard on the surface but stay soft underneath if not baked to harden them. The lacquer is able to penetrate this outer layer and react with the enamel paint.
Only if you prime it first.
What is Acrylic Urethane? What makes it different from Acrylic enamel and Urethane or Polyurethane paint? How does it compare in terms of application and especially hardness to the other two types?
Flashing occurs when a surface has not been properly sealed, so a latex acrylic primer applied over the surface first will keep an eggshell enamel paint from flashing.
Well, honey, technically you can spray enamel paint over acrylic paint on a car, but it's not the ideal scenario. The two have different properties, so the enamel might not adhere properly and could lead to chipping or peeling. If you want a paint job that lasts, I'd recommend sanding down the acrylic paint before applying the enamel.
Acrylic, like enamel paint, can be matt, gloss, or satin finish. Please see the related link below.
This is the common car paint from the 1970s through the mid 1990s It is a development of earlier enamel paints and is still available for those who want it.
