A big priming session today, in difficult conditions and not without its minor drama. Difficult conditions because even though I was priming inside the workshop I had both doors open and it was very windy. Minor drama because just as I started I discovered that the spray gun didn't want to play ball. I had one do this before and it left me stuck: I had to throw away the primer and start again the following weekend with a new gun. Not so this time; I had a spare and quickly swapped over to that and carried on. Lucky these guns are quite cheap, but it doesn't seem to matter how well I clean them, they clog up after a while. This is my third now so I guess I'm going through them at about one every 9 months or so. Still, at NZ$65, its no great hardship. I'll buy a new spare tomorrow!
