If you wanted to blend two wood surfaces which are joined at right-angles so that you finish up with a radiused joint line (i.e. there is a smooth fillet of filler along it), what would you guys use?
I thought I'd be OK using Milliput, but however much I work it according to the instructions, I don't seem to get on with it.
What else is there that easily shaped/smoothed when being applied and can be sanded once it's gone off?
