Primer? or not to Primer?

Sorry, didn't see the post from today about primer...... just read it . Thanks for your replies.

The short answer? Primer. Every time. Primer gives the color coat something to bite into. Also, it helps to smooth over the difference in texture between putty and plastic and anywhere else you have sanded. Use a light gray primer for most colors and white primer for light and bright colors. My favorite is Gunze but you could also use Testor'sMM. BTW, there is no such thing as a stupid question.

The pros and Cons of primers have been discussed in many existing threads, which a quick forum search will produce.
