Well thought my problems were behind me, it seems not
. Can't get the thing to spray again. Was spraying OK, but then started to fade. I assumed this was due to the propellant running low, so changed the can. This did cure the problem briefly but very quickly this too started throwing less and less paint. Obvious conclusion to draw was blockage, so checked everything visually, then tried to put a jar of thinners through it. A quick blob, then nothing. Stripped it down, cleaned the needle, soaked the nozzle cap in thinners for a minute then poured a drop of thinners into the paint nozzle. Reassembled but still nothing. Air is going through it just fine, but no paint? What have I done this time?
