Yup, that's one mistake I always make.. But recently I've been tapping down the metal when I hit high spots. But sometimes that leads to oil canning. And on this roof, I'm dreading it doing that.
But, when I go to apply more filler now, should it just be putty (except for the obvious low spot near the door), or more platinum plus.. I am running out of platinum plus though.
(On another side note, is it ok to go over those bare metal patches with putty? I know it is with filler (obviously) but I've never really used putty).
