It's difficult to believe that this would be an improvement
on wetsanding with 1000 grit. But it's a long tough roud to
get up to where ws'ing w/1k gr will do any good, whereas it
may be that burnishing with bronze wool can bring
improvement right out of the box.

In the past I've never done either. I was using Awlgrip Allstar Gold
Label and rolled it on. This time around I decided to switch to Vivid
which is a hard multi season paint that can be wet sanded and/or
burnished. I was happy with the results but the true test will be next
year to see if it is truly a multi season paint.
