Aileron painting, plus upgrades to paint room

We masked off part of the ailerons and painted them Vestal White.  One of the parts has a paint sag in one area that will need to be fixed (my mistake for spraying a little too thick of a coat near one of the hinges).  More disappointing is that we are still getting dust in the paint which creates even more work for us later.  
    
We decided to stop painting for a while and make some more improvements to the paint booth.  Instead of using air filters from Home Depot, we decided to buy some inlet and exhaust filters from Amazon that are made for paint booths.  The hope here is that we will get improved filtration and better airflow.  We also added a 3rd inlet fan to our room to improve airflow. We also bought some additional rolls of plastic sheeting, and added a layer of plastic to the inside of the room.  This encapsulates the 2x4 framing so that dust can't setting on the framing and later release back into the air.  We should be able to control the dust on the plastic by using a common trick of spraying the plastic with water prior to painting. Hopefully all of these measures will help reduce the dust level in the room.  We wanted to make these changes now before we painted the fuselage and the wings so that we had the best chance of getting a really good paint job on those parts.

While we were making changes to the paint room, we decided to add a couple more LED lights to help lighten up some areas that were a little dimmer.  Good lighting is very useful to see the paint as it's being sprayed, and also to see any defects early on.   Hours: 12
