I had intended to paint them in-situ, but looking closer it was evident the reason they had corroded and bubbled was a lack of undercoat
So I drilled out the rivets - they were held on with the one top plastic rivet and double sided foam down the sides


How they were when they came off the car, some of the paint had already started to come away:

And the aluminium underneath had oxidised beyond belief!

So a quick whizz over with a drill mounted wire brush:

A coat of special metals primer:

And re-paint and fit (this time using a screw driven fastener)
