U channel for rubber seal make/repair on mercedes SL?
Hello all,
Please help me with some ideas on how to repair/fabricate the rusted out U-channel as shown. It holds a rubber seal to stop water ingress into the soft top compartment. Front lip and bottom of the U are cactus ( L) but the rear is mostly intact. The shape is narrow and deep and angled near the car door and uniform for the rest. Construction is as per the sketches. Both layers at the bottom are cactus. All ideas and directions are greatly appreciated. (Edit: I don't know why pics are not shuwing as thumbnails-sorry) Best regards Bernt 20190105_083824-576x1024.jpg 20190105_083834-576x1024.jpg 20190105_083841-1024x576.jpg 20190105_083850-576x1024.jpg 20190105_145104-1024x576.jpg 20190105_145130-1024x576.jpg 20190105_145137-1024x576.jpg 20190105_145217-576x1024.jpg 20190105_145430-576x1024.jpg 20190105_145536-576x1024.jpg

if it was me bernt, i would start with a piece bent as an angle, shape to the contour of what you need, an then using a tool to tip the return flange back up. then follow with a hammer and dolly

Do the Chanel after welding a new piece all along the existing panels, the weld must be about 8 mm away from the existing first edge turn down .You would need to take patterns and profiles first,then cut and weld each piece to the length that you are capable and comfortable to handle.Once the new piece is welded stretch the weld ,then turn the first vertical edge ,shrink and stretch as necessary,once that is done ,then turn the second (horizontal) edge back up, once that is done ,use a block of steel about 2 inches long, but the same width of the Chanel and turn the rest back up just have a look at my post here... title ''torana sunroof'' where I did the Chanel on a roof panel on the existing roof panel

Hi Peter, a reasonable approach but because of the layer underneath (see sketch), I don't think I could turn the 1st edge down in situ.
Unless I am misunderstanding something? Regards Bernt

the only other way then (which would make this a BIGGGGGGG job) would be to find a place where you have access for a dolly in order to planish the weld out, then make a new panel all around then weld it in .Then spot weld the inner to the channel Peter

To Peter, since you've done this type repair before.
I assume that the lip rusted out because of water pooling and wicking back up under the rubber seal. Is it considered a reasonable "sacrifice" to allow this situation to persist or would you consider drain holes (including tubes if draining "inside") or other means of avoiding water pooling?

Marc I would say that the seal was rotten for a long time, If the rubber seal was new, and the channel was clean and painted sooner, I think that the rust would have not come up Peter

And if the seal were sealed with a bit of silicone by factory, so water cannot get down into the channel, then it would also have been ok.
Too late however. Too late also for all the other major rust damage in this car. I now only have this channel and the boot floor and rear end left to do. "Only" Oh, and the soft top cover lid. and... :-(

How about I make an L shape.
Then weld that to the remaining vertical.say ~5mm down with the long leg forming the channel bottom. Clean up the weld and turn up the outer channel edge. What do you think? 1546730139486-834208119.jpg
