Today I went to spray a couple small parts with the white epoxy primer I have (I think I bought it around December, stored inside the house at 70ish). When I started spraying I noticed some specs but then cleared out and sprayed fine.
When I went to clean the gun, it was full of semi-cured stringy sticky goo. Took me an hour to clean a touchup gun since the stuff would not dissolve with thinner. What a mess. The only thing that helped clean the gun was acetone (still would not dissolve it, just breakup in hundreds of solid specs).
The temperature in my shop was 74, parts and primer, hardener and reducer at same temperature since stored inside the house. I mixed the epoxy and let it sit around 5 minutes. Not more than 10-15 minutes in the gun before cleaning. Outside temperature around the same 74.
The only thing I can mention is that I sprayed 2K Regular the day before. Disassembled and thoroughly cleaned the gun yesterday.
What do you guys think happened? I sprayed my whole project with this primer and had never seen this happen. Can it be getting old? Looks good to me (primer looks bright white, mixes good, hardener is straw color and clear as always).
Mixed it 1:1 + 10% Medium Reducer.
