What is the best way to apply and rub filler?

I have been doing a fair bit of welding and have been applying filler as thinly as possible to the area i have welded to make a good surface to paint. However no matter how thinly i spread it, its got great big edges that take an hour to rub smooth to a half decent finish.

I am using Ally Oxide paper as it goes one step beyond normal sandpaper, but there must be a few trick of the trade.

What grade paper are you using?
Start fairly rough and then go fine.

I am using various grades, but even when using the heavy grades its still hard work. I am just being lazy and wondering if there are any shortcuts i can make.

Do you use sanding blocks to wrap the paper round?
The more accurate you can be when applying filler, the less you have to remove to get it flat. You get better with practice, as in all things.
Basically it is tedious, but time spent here gives good results when painted.
