Looks like a struggle George but you'll get'er done.
As far as using superglue for filling, make sure it is the medium or thick stuff, apply it, hit with the kicker. Wait 2or3 seconds and wipe it off and start in with the file. I usually try to finish the filing with in an hour. Deffently don't wait until the next day, and also try to get any sanding done that day. I will usually fill an area several times. Fill then file to the finished level, then hold it up to the light, low areas will be shiny. Fill those areas and file again and take a look. Repete if need be. It sounds like a lot of work but it isn't and goes very quick with the kicker. I could do the a small area in the time it took me to type this
