Are there any articles or threads that explain how to paint lines start to finish. I can mask off a line and paint it but it has ridges so, must be some trick to it I don't know.

Thanks,

credit card trick may help knock them down. Too thick of a coat will make it very difficult to remove them. Use thin paint, build them up with 3 coats, let dry, you can even lightly scuff the color with 1500. After that spray with clear 50/50. 4 coats. Skuff sand clear with 1200. Then spray one or 2 wet coats over it

Like if I have a white fuselage and I want to put a blue stripe on it.

It depends on the colors.  For a dark stripe over a light color I do it Brett's way.  For a light stripe over dark colors I paint the stripe first oversized then mask it and paint the dark colors around it.  If I am using Red and I want a white stripe I use white for the masking color and do the whole plane with just enough extra color around the stripe.  Yellow is another color that doesn't hide changes in background color quickly.
