Battery tray and clamp respray:
The battery tray was spoiling the look of otherwise relatively clean engine bay, here they are just taken out of the car (the "before"):
I've decided to remove the rust chemically (using Deox C), 5 minutes in and you can see the rust starting to come off:
1 hour in Deox C:
2 hours later, after a bit of scrubbing with scotch brite pads and soaked in batch of fresh Deox:
Then I used wire brush and 200 grit sand paper, degreased all the bits and cleaned them up with white spirit just before the primer, here is the tray sprayed with Zinc etch primer:
Tray and clamp after few more coats of regular primer:
Little bonus - dynamic dumper that's part of the engine mount - also looking shabby:
All paint removed, ready for primer:
Primed, ready for top coat:
And the finished product (the "after"):
Not sure about the gloss black paint, think it might be little too glossy, satin would have been better, other than that I'm delighted with the result. Wish I had a plating kit at home so that I could do the bolts right (zinc plate and passivate them - to get the "gold" OEM look)
