I'd like to share two painting tips that I recently had to learn the hard way. The first I learned years ago in my oil painting class, but I seem to have forgotten. I was working on my Malanthrope the other night and thought it looked pretty good. The next morning it looked completely different! The reason why was at night I paint by warm yellow indoor lighting, and in the morning I get cool reflected skylight through the patio door. I learned this in college but forgot my lesson. So be aware of your lighting as it differs during the day.
Secondly, I was wondering why my paint was coming off in certain raised areas on the Malanthrope. I realized it was because I was handling it excessively. This has never been a problem before because most models have a base that you can handle. Not so with my dear 'thrope. Mine is magnetized to the flying base for ease of transportation. So now I have to paint extra cautiously and slowly as it sits on the flying base to avoid hand contact. Pay attention to how you handle your models, as the oils on your skin can be detrimental to the paint. Sealant can stop this problem, but unfinished models will suffer.
