So i made a terrible terrible mistake and while prying off my dust seals to clean out the grime from my forks on my KTM, my screwdriver slips and i nicked the fork stanchion. I really lightly sanded with 1500grit and am taking apart my forks anyway to put in new seals.

Doesn't look too bad, but if you can feel the ridge it will probably wear out a seal faster. If it's deep, put a little super glue on it and sand down with very high grit sandpaper and should be fine, done all the time. If not, just sand it.

I have fixed a number of scratched tubes. As long as the scratch doesn't go through the layer of chrome; this method works very well:
Murdercycle
Well no pics turned out, the scratch is barely just visible now. if it is still leaking, il attack it again but not dissasemble the forks this time. I went at it with a sharpening stone very gently, then 600 grit then 1200grit then polishing cloths. it is really hard to see and i cant feel anything. Il get pics when the light is better in the day.

Many times you can buy just the chrome slider from the OEM, so if all else fails, you could just replace the lower/slider portion.

If its not too deep of a scratch, what we do to out mtn bike forks when they get scratched is to clean the area well, carefully apply a little clear nail polish to the scratch to fill it in and once its dry take fine like 800 grit wet/dry sand paper or scotch brite emory cloth and carefully sand the area to smooth it out and blend into the rest of the stanchion tube. You just want to smooth it out so it doesn't cut your seals.

What to do if JB doesn't stick?
If the JB doesn't stick, just resand and leave the tiny gap open. With the edges knocked off it won't tear the seal and it can only leak the volume the gap holds each compression stroke that causes the seal to cross the gap. Maybe slightly faster seal wear, and f that is a problem, you can always attempt to fill it again. Hopefully the JB holds. Pretty good at sticking to clean metal.

JB Weld may be smooth but it will never be slippery like the surrounding fork tube.
ossagp1
True but the area is smooth enough and small enough that I am not noticing any stiction (yet). Long term repair is still up for debate, so i will try to report back after some abuse.
Suspenders
I have repaired dozens of them with two part plastic epoxy. Usually two or three coats. Spin sand them with wet dry and over the years I had one come back that did not hold. Stiction is not a concern.

How did you spread that weld on? I am about to do this fix on a dented fork tube.
