Flatten plastic primer before filler primer on plastic?

[sgtBerbatov]

On my car (which is far from concourse) it has some black trim on the bumpers which I want to paint white to match the rest of the bumper. I'm going to apply a coat or two of plastic primer first, and then some filler primer to make the textured black part smooth.

The question I have though is should I flatten the plastic primer before applying the filler primer? Or should I leave it and just apply the filler primer afterwards?

Profile it as best as you can first

Sorry, misread it while I was half asleep. Thought you said primer over filler!

Don't flat it, just apply the next coat as soon as it's cured and is still clean.

yeah let the plastic primer flash /dry off for 10 mins then on with the primer

key the plastic first though

Just a follow up on this, I followed the advice here and this is the result. Proper chuffed!
