I hope someone can help. Last night I had a major paint spill while painting a model. There was a major clog and I tried a back flow and it went everywhere. Finally got it working and there was still a lot of paint in my cup so I kept going. When I finished I dismantled my Iwata cleaned it and put it back together. Now it will not spray. When I press the button down I get air (dual action) but when I pull back there is air but no paint and it bubbles back into the cup (doing the back flow thing) any help would be really appreciated.
