I hope I am not bothering you to much with this but as you do a lot of painting I am sure you can answer my question. When the Twin Otter Extended came out I asked a gentleman about doing a paint. He did it for me and I fly this aircraft all over Montana.  My question is what would the process be to Make this paint a Tundra.  I may have answered my own question but want somebody that does a lot of paints to tell me.  I know it is not hard to change a passenger paint to a cargo but I m sure paints are different.  I am not a painter so not sure what the process is to change from a regular to a tundra. Thanks
