Good evening fellow Copen fans. Buzz has been off the road since the end of January and tucked up nice and cosy in our garage since. When I was changing his wheels last week, I was horrified to notice that surface rust had appeared in the rear wheel arch area. So, I decided to take a proper look and take some action. The metal is strong and solid, not rotten, but as the photos show, ugly orange rust patches have started to develop. I've used Jenolite previously on my old Austin A35, and it worked really well, so I bought some from Ebay and gave it a try earlier today. The attached photos show the process, with the last photo showing the end result. I would really appreciate any comments that other members may have, particularly regarding the next steps on from here. Cheers! PhillandLin and (rusty) Buzz
The jenolite converts rust into a kind of black oxide which is a stable surface but you shouldn't just leave it like that. If there are still spots of rust showing go over it all again with the jenolite making sure you stipple the stuff well in with your brush. There will probably be a certain amount of rust creep under the underseal at the edges of your repair. If any underseal isn't well adhered at the edges of the rust you should remove it and treat underneath. The next thing is to put a coat of underseal over your repairs to protect it. Black underseal or a wax based coating like Waxoyl is the stuff to use. Waxoyl is better than underseal, it's self repairing. Use black Waxoyl or similar for exposed areas like you have.
I agree with DaG. Did you remove any rust before hand? although the brown you see might be converted and become stable, thicker rust will possibly have untreated rust underneath the black layer. Also its quite porous, so you would really need to cover it with a non permeable layer, like paint then clear coat. The edges of the black with still be a sit for moist to attack and cause rust to continue. Its ok but not a complete problem solver. it does look better after its added though so its a nice uniform black. Its not the colour brown that gives that ugly factor, its the knowledge of what it is, and you know it just mean issues
Well less about your bathroom regime Adam, stick to cars But Adam's underbody hasn't gone rusty. On the last report anyway
Jenolite type products need rust to work, they don't work very well on nice shiny steel but it's still best to wire brush any loose surface rust to reduce the deposits before treatment.
