I haven't used the 410, have used the 407. If you plan on just using it to fair out a joint or make fillets, it will work fine. If you want to do anything that is more structural, I'd go with the 407 instead. I primarily use the 407 for low stress areas and 406 where I need a bit more strength.

It is tougher and lighter than bondo and can be mixed to the about the same consistency and applied with a stiff spreader. I save my old utility knife blades to use as spreaders.
