Well, the flex is not a worry for me with the sections I'm painting. The paint I use is automotive paint, which has some flexability. I'm not set on the color yet. Like I said, work in progress, I didn't think about orange, which is one of my fav colors. I may re think my color scheme, I just want sometning that goes well with green. That section of my plastic was a little dull, so I fig why not. I'm just trying to make a one of a kind. Something different. I won't paint anything on the fenders, they take to much of a beatin from sticks and mud. That is why I did the parts I did. I can change the color easy enough. If I don't like any other color, I can go back black. But, I don't want to paint the other pieces until I find the color I like. I am ok with silver, just because it will go with anything. But curious of what other colors might look like. I wish I had a photo shop prog that would do that kind of stuff, I would know with out all the work.
