I think so, yes. The tubes are like $11, and what the advantage is, is that they have a replacable gasket that have pre-cut holes in them that you push and then pull the arrows back through - this gasket is a squeegie and leaves a very thin layer of laquer, equal on all sides, on your arrows. Gasket Laquer dries amazingly fast, so fast (and thick) theres no way to let it drip. Gotta have dip tubes with the gaskets IMO.

Now for the minwax polyacrylic, I use a capped off, super funnel you find at WalMart auto center. It, unlike GL, will drip off evenly.
