I'd call General Finishes to ask the question, but it's a Sunday and I have to do it now. I'm spraying a General Finishes topcoat called Enduro-var ii, a waterborne finish. It has a 2 hour wait until you can put the second coat. My question is: how long can you let unused Endurovar sit in the spray gun can before you start to see problems? The bulk Endurovar comes in a metal can and it doesn't harden. So it seems to me a couple hours in a covered can won't hurt it and after some stirring should be ready to go. I probably wouldn't let it go much longer. Or should I drain the Endurovar, and flush the spray gun after each coat? Thanks for guidance on this issue.
