Of course, that primers grey, and its 2 pack, and here's the next idiot mistake.
There was a small, pea sized dint in the roof, enough to be annoying but that I had missed previously.
I tried some stop putty, hoping future coats of paint wont eat it. It sanded nice, and had been given plenty of time to fully cure.
Since I'd painted the side of the van and door, may as well dab a little of the grey primer on to seal it, right? Save me mixing up some white.
I expected the topcoat might show the grey slightly, but gave it a crack anyhow:

Here you can see a ghost image of a cat where they grey undercoat is shiming through.
Bugger, because it was getting there apart from the odd run.
I'll try an patch spot a few coats, but i think the roof will need a full coat again.
Maybe leave it now for winter. We'll see.
The roof rail repair spot looked ok too.

And another thing I should have done, was defluff the roller first, but would you believe I ran out of masking tape.
You can see the little specs, like dust in the finish. Could have been dust as it cured.
Lucky its getting painted again....
that its for painting.....
