I've now been using throw-away (cheap) brushes for applying gloss polyurethane to the canes for several good reasons. a) spray gets on everything in the vicinity I like the look of hand applied poly vs sprayed - for I can control the depth, etc.
But here's the issue with brushes vs spray - what to do with those brushes between coats - sometimes 24 hours apart. I'd like to use each brush for the completion of the project, then dispose of it but keeping them soft and supple has been difficult.
For a bit I was swiping the excess polyurethane away and then dipping it into paint thinner and leaving it to dry. Most recently I've been wiping away the excess and then sealing the brush inside a ziplock bag.
But I'm still searching out the best way to keep used brushes between coats.
Any suggestions, guys?
