Does it need primer coating befor applying the 3m silencer spray?

No. You can spray it directly on the surface. Remember, the cleaner the surface to coat, the better it last.

can I use this for bullet silencer and engine

I guess, this must be stainless steel. If so, you can paint, but it won't stay for long.

It can be used for motorcycle engine painting

Yes, you can use, but it will give matt black finish not the shining one.

What is the problem of using it in bullet silencer

You can use, but it will take 5-6 coats if the silencer is of chrome finish.
