This is a PDF from Uniters sent to me, explaining how they recommend their edge paints are applied and finished. As far as I'm aware it's freely available to all on request, but they don't seem to advertise it.
Interestingly they are the first I have seen to recommend finishing an edge using heat. They also state the maximum heat to use which is helpful.
What do you think if 'You can bush or buff by rotative brushes'? I have experimented with this in the past with excellent results.
I use a bench grinder and a small felt wheel with a channel removed in the desired shape.
It quickly uniforms the edge, but can just as quickly destroy your work if you're too slow (friction heat build up).
Funny part? 'Let it dry properly (15-20 minutes)' 😂. Maybe in the Sahara desert, but no chance during a damp English winter!
Wait 15-20 hours they mean? Last week, i sanded an edge 4 hours after painting, it was still liquid from the inside...
I am curious about the buffing, i will definitely try it soon!
