While washing the car a few months ago, I noticed some of the paint peeling off the rear arches.
So, over the weekend I got the car up on stands, and got under there with the power washer. All cleaned, then moved the car into the garage to dry. Once dried, got in under there with the Dinitrol and got everything nicely waxed.
I'd just like to thank Opel for the totally useless job of undersealing they did:
-The area round the rear shock mount is not only not undersealed - it isn't even painted! Bare galvanised metal.
-The stupid plastic cover over the hole into the sills are flapping in the wind, holding enough soil and stones to grow a small potato plant. So, that was all removed, cleaned and Dinitrol'ed.
-The loose paint was removed round the arch, masked and painted with a thick covering of wax until the summer when I can prepare it properly for spraying.
-Wheel tub at the back is also down to bare metal just from the crap hitting it from the wheel. That was also roughly cleaned and waxed to stop it rusting any more until the summer.
There wasn't any rust on my old Vauxhall built Mk4 after 5 years, yet this Opel built one is rusty in several places after just 37 months. Not happy.
Spoke to Vauxhall about it - paint is a 1 year warranty, and the rust warranty only applies when it goes into a hole. Whoopie!
No pics, as I didn't have my camera with me when I was down at my folk's house doing the work. Sorry.
