I am in the process of doing a little kit bashing to create a skeleton log car. I have a question on fastining a metal part to a plastic part. Everyone says "Paint the plastic before assembly" My question is "Will painting the plastic before I glue the metal part to it, reduce the bond of plastic to metal? Should I paint before or after gluing?

FYI: The plastic part involved in the gluing is not on a sprue. I can easily paint before or after the gluing. It will be airbrushed.
 
Whenever possible, paint after construction. That way you can fix any flaws, rough spots or glue marks first and not mess up the finish. I usually pre- paint only what would be hard to paint after assembly.

Glue first paint later.
The glue will remove dried paint and make a small mess.

Also smeared glue can be fixed with a coat of Testors Dull coat, hides it well.

I always finish builds and cars with a liberal coat of Dull Coat.

Metal to meatal and joints with stresss I use 5 minute epoxy. It is esential for glue broken couples and meatal parts on engines of any gauge.

Now these are things I do and that work for me.

Others may have better or differnt tricks.
 
Don't paint the surface to be glued.
Think of the following:
-Try to paint flat surfaces before assembling into boxes.
-paint before assembly if the colour changes at the joint.
-paint after assembly if the colour goes around the corner.
(yes, I know I've contradicted myself!)
