Nice project and a lot nice work.
Have you tried this stuff for windshield channels and pitted metal?

No haven't. How difficult is it to spread smooth and sand?

It's not difficult to spread, but you can only mix a little at a time as it dries fast and also doesn't take long to sand if the temperatures are right.
I normally clean and acid treat the area, then buzz it with 80 or 60 grit and apply the filler with a cut down piece of spreader to the width of where it will be used, keeping the passes tight for less sanding.

It's pricey for the amount but I think it's worth it.
Here it what the new label looks like.

Here it is.

Thanks! I will look into it as I still have to remove the front glass and I have zero expectations that it will be pristine?
