The regulations talk about building an experimental aircraft ...."that the project is for educational and recreational purposes;"... boy. am I getting educated! My technique is getting better but I have made most of the common errors as I expected.My new education will be fixing the common painting problems..sags, fish eye, orange peel, etc. I am using a 3 part system; chromate primer, color coat, and clear coat. The paint has a high gloss finish already but I am clear coating to give my self some working room. This will be in the finishing and buffing area. I will be able to fix most of my errors at this point. My goal is to get the aircraft airworthy soon and then, over time, deal with the finishing. Safety is important so I purchased an external breathing air system. I wear a chemical mask under a paint hood which has the external air pumped into the hood. When I exit my booth I can safely disconnect the breathing air and exit with the hood and chem mask. All doors in the hangar are open to vent the filtered fumes from the booth while painting. The hangar also has an evaporative cooler to pump filtered fresh air into the entire hangar.
