Vern, this stuff is so thin, that it would be very difficult to use it to fill pits. It'd take about 5 or six coats...maybe more...even for a little one. I have never tried sanding it either.
The color is entirely consistant to the best of my observations, though, as I have said, I've never tried sanding it to see for sure.
I believe it can be cured at a lower temperature, if the bake is longer, as I have heard of people doing this on plastic componants, and even optical systems, though I personally haven't tried either. They also offer a new "air dry" variant which you may want to look into which cures at room temperature.
The only thing I've ever done to protect the barrel is to plug either end with a small bit of cotton, or what ever I have lying around.
