rodger. Posted June 21, 2015 Report Share Posted June 21, 2015 This can of general HP poly is not very old, and I take good care of my cans and finishes. Check out how much crud I filtered out (after stirring) before loading my spray cup. Quote Link to comment Share on other sites More sharing options...
wdwerker Posted June 21, 2015 Report Share Posted June 21, 2015 Lumps and foreign matter cause spray guns to clog, spit and sputter (usually at the worst possible time) I have noticed that water bourne finishes can skin over if you leave the lid off. If I pour and filter a second cup for a quick change/refill when spraying a large project I cover it with a lid or damp clean rag. Quote Link to comment Share on other sites More sharing options...
