The tank requires a lot of work that I have never done before. Filling dents with a two part epoxy that will become virtual metal so that it can take powder coating was new to me. Not so much the filling but the waiting overnight for it to dry and then very difficult sanding because it is so hard, like metal of course. Then you can feel with your fingers that it needs a little more, so fill, wait overnight and remove your fingerprints with the constant sanding! So the breaks in the waiting preparing and spraying other parts was a real joy.
