I made this tool from a piece of scrapped truck spring. It's about 4 lbs and I ground away the inner curve at the bottom to fit into the crease of the door skin and luckily, the rest is the curve of the door bottom up and past the welded repair seam. One guy gets in the car when it's hung on the hinges and another guy outside slaps over it and files a little to find the low spots. Ear, eye protection and gloves a must!
I can do the majority of the skin myself that way when the car and door is on a lift, but another set of hands works well in the hard-to-reach forward areas no matter what.
As far as 'slick' (polyester filler putty) goes for the small amount of surfacing, the old adage was that "an eighth of an inch is commercially acceptable" and Ferrari used a sprayable filler that thick on some of their cars I've worked on. Most all bodyshops use at least SOME filler, but that's when talent and time are in short supply. Most filler ends up on the floor and a little here or there is not a crime if done to a minimum and done well...and a 32nd can be considered 'just something to sand' to get it smooth.
Go figure; famous car people like Junior Conway use many layers of sanded paint to get a sm-o-o-o-th finish....and if the 356 is to be driven....well, just "git-r-done."
