Wet feet so had a look and found this.
Started cleaning it up but got some fun ahead.

Did you re-weld (enclose) that channel or leave it open? From the pictures it looked like it is left open. I probably have the same repair.

Is there a reason to leave open vs. re-enclosing it? Is the enclosed channel structural support? Just curious.

I just left it ("for now" (,but in all honesty will probably leave it that way permanently)) for easy access in case of a future leak problem. Yes, for structural reasons you'd be better-off welding it back together, but I believe the wheel-well area repair is more important for structure. It's entirely up to you..

thanks for the pictures smoothie. I was wondering what that channel was like on the inside. I have a battery tray repair job ahead of me.
Just as a note on something to look for with water leaking in from the battery tray. Both my 924 and my 931 (aside from the normal battery tray rust problem in the right front of the tray) had stress cracks in the left front of the tray just before and about where it starts curving up towards the heater fresh air inlet. Not rusted just cracks. Thats actually where the water was getting through on my 931. There were no actual rust holes.
ps. I hate battery trays! . . . actually I hate rust, but aren't those two words almost synonyms?

Hey Smooth Dog,
Based on all you went through here, if you had a pristine battery area, what preventative steps would you take with it? I happen to have a can of seam sealant sitting in my garage. . .

Well, knowing what I know now I'd try to get a look inside that channel for any signs of rust. Mine was apparently not painted, not undercoated, not anything inside there by the factory, so it's a great place for rust to start. Remove the battery and pull off those little plugs and get a look inside as much as you can (which won't be much of a look). You could also scrape off whatever seam sealer there is along the seams outside of the channel to see if there's any rust starting under it. If you find any at all, consider opening up the channel some to get a better look and access inside to do some cleaning, rust treatment, coating - no need to open it up as much as I did - maybe make an oblong opening removing the metal that the inspection holes are in that will give you enough room to see, fit in a brush, do some rust treatment, spraying, bodyfiller, whatever's appropriate. -Or just shoot some rust treatment followed later by undercoating in through the little OE holes, hope for the best, then do the full cutout and repair further on down the road if it becomes necessary. I found what looked like a minor seam problem a couple years ago, dealt with that, then this last fall was suprised by the much more serious rust in the same area.
In the wheelwell area, press in around that area that I cut out and replaced. If the metal behind is rusted badly enough, you'll hear it crunch and feel it move. In about a 2" diameter spot there behind the wheel, all I had was the factory undercoating which looked fine, but you could press in on that spot because the metal behind was rusted out.
Those areas of the fender and adjacent door jamb and body where I found rust seem to be common rust areas. You'll be able to see any damage at the bottom where road grit/dirt accumulates, but the rear of the fender where it's bolted to the door jamb is invisible until the fender is removed. I caught mine in time so a cleaning with naval jelly was all that was needed (followed by the PPG metal treatments, POR15, and undercoating), but as I recall, 924guy in Fla found his rusted through in that area to the point were some cutting, grafting and welding would be needed. Nice to know my right side is ok now, but I still have the left fender to wonder about..

Ok- I am trying to remove the LH wing, fender, mudguard.
I have all the screws off at the front and top.
I have one screw removed from the bottom at the back.
Before I start pulling at it - is there any more?

i assume you've looked here
http://www.924board.org/viewtopic.php?t=20669
for where to find all the fender bolts.
apart from that i guess you just have to pull carefully and hope.
good luck mate

These are the more hidden ones -

Feel for 3 bumps aligned vertically, behind the fender and facing the rear through the undercoating. I had to scrape some of the undercoat off first to get a socket wrench on them. You can get an idea of where they are by the 3 holes shown in this pic -
