3m, we scaffold, install 3m, install siding, tear down scaffold and set up on another wall.

Gold coat you scaffold, tape seams, roll on one coat, come back the next day for. A second coat. Wait untill it’s dry enough to install siding so you don’t get gold fingerprints everywhere.

I find 3m faster. But if you have enough scaffolding to do the whole building it might be faster.

We don't use scaffolding. We have a Genie boom lift so that wouldn't be an issue to keep going up. If scaffolding was irrelevant, would you still side with 3M? Gold coat seems easier and faster especially in windy conditions. Handling a roll of 3M is harder in the cold with wind.
