At long last today I decided it was time to finish the clearcoat on my SF2 playfield.
I spent my spare time over the last few days setting up my spray booth. The last time I tried to paint in my shop, I think I got more paint in my shop than on my playfield.
I mixed my paint like I have in the past, using Omni mc730 clear with mh738 hardener and mr295 reducer. It was a nice 65 degrees in the shop when I started painting.
I cleaned my playfield with naphtha (camping fuel here in California) and set my gun up for a heavy coat.
Then disaster stuck... Fisheye, and in a big way.
So what caused the contamination? I don't think it was the compressor, the air filters are almost new. My best working theory right now, is that the rags are used to clean the playfield were contaminated. I use recycled rags that have been washed. I might have picked up one that was used to wax a play field.
Does anyone else have any suggestions for avoiding fisheye in the future?
For now, it looks like I will have to start sanding it back down in a day or two.
