I have to paint/treat thirty 6x6 fence panels in situ and would
welcome any advice from the group on the easiest method of doing this
to get a good finish ...... brush , spray , roller etc.
I've used Cuprinol Ducks Back in the past which is good & covers well
but I think you have to use a brush which would be an extremely
labour intensive task.

Ducks Back is available as Cuprinol Rollable in square tubs.
I treated ten 6x6 panels both sides using this - it took two tubs and it was
a soul-destroying nightmare.
Getting the stuff into corners and crevices still has to be done with a
brush.
Once the panels were installed the lapped areas moved in a gale and I had to
go back and brush over the bikini lines that resulted.
I've now done another five panels using brushable Ducks Back - which seems
to be the same product! I hired a spraygun to use with it, but it just kept
clogging up. So these five were done by brush, which used half as much again
as the roller (but at least it seeped under the overlap - so hopefully no
bikini line!)

If I were to do it again I would use a spirit-based treatment and an airless
spraygun. But now I'm stuck because I won't be able to match the colour.....
